If 12% of the cost price of a good is same as 10% of its selling price and 15% of the cost price is ₹10 more than the 12% of the selling price then what is its selling price.
Answer & explanation
Correct answer: option 3
12% of the cost price of a good is same as 10% of its selling price
12% CP = 10% SP
12 CP = 10 SP ----(1)
15% of the cost price is ₹10 more than the 12% of the selling price
15%CP = 12%SP + 10
15CP = 12SP + 1000 ----(2)
multiply equation 1 by 6 and equation 2 by 5 , and then subtract
72CP - 75CP = - 5000
3CP = 50
put in equation 1 ,
4 × 5000 = 10 SP
10SP = 20000
SP = 2000
The correct answer is Option (3) → ₹2,000
