Question

a toy car is sold at a gain of 16% has it been sold for ₹ 100 more the gain would have been 20% find the cp of the toy car

Answer 1

the price of the toy car is 400

this is how

x is the c.p

y is the gain

16/100*x= y

20/100*x=(y+100)

solve this and you will get 400 as x

Answer 2

let the sp of the car is x rs
then the cp of the car is x × 100/116
=100x/116
if the sp of car 100rs more
then it cp is,(x+100)×100/120
the cp of car is,
100x/116=(x+100)×100/120
=>100x/116=(x+100)×5/6
=>600x=580(x+100)
=>600x=580x+58000
=>600x-580x=58000
=>20x=58000
=>x=58000/20
=>x=2900
therefore, the cost price of car is 2900rs
