Question

Raghuvir bought 10 calculators and 16 watches for Rs. 56000 and sold them at an overall profit of 20%. At what price should he sell 15 calculators and 24 wathces so that he receives the same percentage of profit ?

Answer 1

Answer:

100800(100800)

Step-by-step explanation:

The price of one calculator=x rs

The price of 10 calculator=10 x rs

The price of one watch=y rs

The price of 16 watch=16 y rs

Given-The total price of 10 calculators and 16 watches=10 x + 16 y=56000 rs

2(5 x+8 x)=56000

5 x+8 x=28000

So the price of 15 calculators and 24 wathces -

(5 x+8 x=28000) x 3

15 x + 24 y=840000

Because he sold them at an overall profit of 20% so-

(840000 *120)/100=100800 rs
