Question

lemons are bought at the rate of 3 for 4 Rupees at what rate must they be sold to gain 20%?

Answer 1

if, cost of 3 lemons is 4 , then the cost of 1 lemon will be 4by 3which is 1.3333.....Then
here Cp=4 /3 ,gain =20%
the formula to find Sp when gain is given is
Sp=100+gain%/100×Cp

which is:-
SP=100+20/100×4/3 (CP GIVEN)
SP=8/5 which os 1.666666.....


Hence ,the answer is 8/5 or 1.6

Answer 2

Answer:

Cost price of 3 lemons = 4/3

S. P = 100+Gain/100* C.P

(100+20/100)*4/3

= 120/100*4/3

= 40/25

= 5 for rupees 8
