Question

if two numbers are in ratio 3:7 and their sum is 140 , find the numbers

Answer 1

question:-

if two numbers are in ratio 3:7 and their sum is 149, find the numbers.

AnsWer :-

42, 98

let the number be X

so,

3:7 will be 3x and 7x

now find the two numbers?

$= \geqslant 3x + 7x = 140$

$= \geqslant 10x = 140$

$= \geqslant x = \frac{140}{10}$

$= \geqslant x = 14$

hence the two numbers will be :

• 1st = 3 × 14 = 42
• 2nd = 7 × 14 = 98

Answer 2

1st = 3 × 14 = 42

2nd = 7 × 14 = 98
