Question

Number "85" is divided into two parts, such that thrice the first part and twice the second part are in the ratio of 18:5. Find the first part ?

Answer 1

Answer:

Let

1st part be X

2nd part be = 85 - X

Given,

$\frac{3X}{2(85-X)} = \frac{18}{5}$

=> 5 × 3X = 18(170-2X)

=> 15X = 3060 -36X

=> 36X + 15X = 3060

=> 51 X = 3060

=> X = $\frac{3060}{51}$

=>  X = 60

First = 60
