Question

18 A tricycle is sold at a gain of 15%. Had it been sold for 27 more, the profit would
have been 20%. Find its cost price.
​

Answer 1

Answer:

Cost price is Rs. 2160

Step-by-step explanation:

Let cost price = x

If it is sold at 15% gain,

15% of x = x × 15/100 = 0.15x

selling price = x + 0.15x = 1.15x

If it is sold at 20% gain,

20% of x = x × 20/100 = 0.2x

selling price = x + 0.2x = 1.2x

Given that

1.2x - 1.15 x = 108

⇒0.05x = 108

⇒ x = 108/0.05

⇒x = Rs. 2160
