Question

A person allows a 10 percentage discount for cash payment from the marked price of a toy and still he makes a 10 percentage gain .what is the cost price of the toy which is marked rs 770

Answer 1

LET C.P BE X

THEN,

PRICE ON WHICH THE TOY IS SOLD = 110X/100

MRP = 770

DISCOUNT OF 10% ON MRP
= 770×90/100
= 693

PRICE AT WHICH THE TOY IS SOLD = 693

THAT MEANS,

$\frac{110x}{100} = 693 \\ x = 693 \times \frac{100}{110} \\ x = 63 \times 10 \\ x = 630$
CP OF THAT TOY IS 620.
