*Profit & Loss Tips & Tricks*

*Profit/Loss is another easy topic of Bank & SSC Exams. Most of the questions can be solved in less than 30 seconds. First let me introduce a formula that will be used in solving 50% of the questions.*

* *

*Where,*

* SP = Selling price*

* CP = Cost Price*

* f = Profit/loss factor*

*What is this profit/loss factor ? It’s simple, ‘f’ depends on the profit/loss %*

* If profit% = 10, then f = 1.1*

* If profit% = 30, then f = 1.3*

* If profit% = 15, then f = 1.15*

* If loss% = 10, then f = 0.9*

* If loss% = 25, then f = 0.75*

* If loss% = 12.5, then f = 0.875*

* Please note that f depends on profit/loss percentage and not on the absolute value of Profit/Loss. So if in any question it is given that the profit is Rs. 30, then it doesn’t mean that f = 1.3*

*Let us see some SSC CGL questions that can be solved with this formula*

**1**

*Let ‘s’ be the SP of 1 article and ‘c’ be the CP of 1 article.*

* Given, 6c = 4s*

* Therefore s/c = 1.5*

* Gain % = 50*

* Answer : (B)*

**Q .2.**

*Let ‘s’ be the SP of 1 metre of cloth and ‘c’ be the CP of 1 metre of cloth*

* Total SP = 20s, Profit = 4s*

* CP = SP – Profit = 16s*

* The ratio s/c = 20s/16s = 1.25*

* Gain % = 25*

* Answer : (C)*

**Q . 3.**

*SP of 1 article(s) = Rs. 10/8 = 5/4*

* CP of 1 article(c) =Rs. 8/10 = 4/5*

* s/c = 25/16 = 1.5625*

* Gain % = 56.25*

* Answer : (A)*

**Q) 4. Kunal sold a shirt at a loss of 10%. Had he sold it for Rs 60 more, he would have gained 5% on it. Find the CP of the shirt.**

*In this question we have to find the CP of the article*

*c = s/f*

* From basic mathematics or elementary science we know that putting delta (∆) sign in numerator and denominator doesn’t change the equation. ∆ stands for ‘change’*

* c = ∆s/∆f*

* where ∆s = change in SP*

* ∆f = change in factor*

* Therefore ∆s = New SP – Old SP = Rs. 60*

* ∆f = New factor – Old factor*

* New factor is the factor when profit is 5%. Old factor is the one with loss = 10%*

* So ∆f = 1.05 – 0.9 = 0.15*

* c = ∆s/∆f = 60/0.15 = Rs. 400*

* Answer : Rs 400*

**6)**

*CP of 1 article = Rs.8/10 = Rs. 4/5*

*SP of 1 article = Rs. 10/8 = Rs. 5/4*

* SP/CP = 25/16 = 1.5625*

* Hence profit% = 56.25*

**Answer: (A)**

**7)**

*Total investment = Total CP*

* Let the CP of 1 egg = C*

* Then total CP = 200C*

*Total eggs left = 200 – 38 = 162 eggs = 162/12 dozen*

* Total SP = (162/12)*4.8 = Rs. 64.8*

* f = 1.08*

* Hence CP = 64.8/1.08 = Rs. 60*

**Answer: (D)**

**11)**

**This question appeared in Tier-2 2014 and is one of the trickiest question asked by SSC from this topic. So much so that many question banks haven’t published its solution. Although if your concepts are clear, then there is nothing tricky here.**

*Let the fruit-seller buys 100 oranges*

*Now, he has sold the oranges in two parts. First he sold 40 oranges and then he sold 48 (80% of 60) oranges.*

*Total SP = (SP of 40 oranges) + (SP of 48 oranges)*

*Given, SP of 40 oranges = CP of 100 oranges*

*40S = 100C (where S = SP of 1 orange and C = CP of 1 orange)*

*S/C = 2.5*

*f = 2.5 and hence Profit = 150%*

*He sold 80% of remaining oranges at half the previous rate of profit.*

*That means he sold 48 oranges at 75% profit.*

*CP of 48 oranges = 48C*

*f = 1.75*

*SP of 48 oranges = 1.75*48C = 84C*

*Total SP = (SP of 40 oranges) + (SP of 48 oranges) = 100C + 84C = 184C*

*Total CP = 100C*

*f = SP/CP = 184C/100C = 1.84*

*Hence profit = 84%*

**Answer: (B)**

**TRICK-1**

**If two article are sold at equal prices, the first one is sold at P1% Profit and whereas the second one at a Profit of P2% ****And the sum of the cost price of two article is x then**

**For Example:**

*(Q1) A trader bought two watches for Rs 2300. He sold one at a profit of 10% and the other at a profit of 20%. If the selling price of each watch is the same, then their cost price are respectively.*

*Solution: By Trick:*

*C.P of watch at a profit of 10%=((100+20)/(200+10+20))×2300*

* =(120/230)×2300*

* =Rs 1200 Ans.*

*C.P of watch at a profit of 20%=Rs(2300-1200)*

* =Rs 1100 Ans.*

*BY CONCEPT:*

*Let C.P of 1st watch=x*

*C.P of 2nd watch=2300-x*

*S.P of 1st watch:*

*Now According to question: selling price of each watch is the same*

*SO,*

*S.P1=S.P2*

*11x/10=(2300-x)×12/10*

*11x=2300×12-12x*

*Solution: By Trick:*

*C.P of T.V at a Loss of 12%=((100-16)/(200-12-16))×21500*

* =(84/172)×21500*

* =Rs 10500 Ans.*

*Solution: By Trick:*

*C.P of horse at a profit of 25%=((100-15)/(200+25-15))×16800*

* =(85/210)×16800*

* =(85/210)×16800*

*Solution: By Trick:*

*C.P of horse at a Loss of 20%=((100+15)/(200-20+15))×19500*

* =(115/195)×19500*

* =Rs 11500 Ans.*

*Solution: BY CONCEPT*

*Let C.P of 1st watch=x*

*C.P of 2nd watch=840-x*

*S.P of 1st watch:*

*x×(100+16)/100=S.P1*

*116x/100=S.P1*

*S.P of 2nd watch:*

*(840-x)×(100-12)/100=S.P2*

*(840-x)×88/100=S.P2*

*Now According to question: There is no profit or loss*

*SO,*

*S.P1+S.P2=840*

*116x/100+(840-x)×88/100=840*

*116x+840×88-88x=840×100*

*Solution: BY CONCEPT*

*Let C.P of horse=x*

*C.P of a carriage=40000-x*

*S.P of a horse:*

*x×(100+10)/100=S.P*

*11x/10=S.P*

*S.P of a carriage:*

*(40000-x)×95/100=S.P*

*Now According to question: he gained 1% on his whole transaction*

*So,*

*S.P of a horse+S.P of a carriage=40000×101/100*

*11x/10+(40000-x)×95/100=40000×101/100*
