Question

Arun saved 2/7th of this income and Geetha saved 9/10th of her income. Who saved more and by how much?

Answer 1

Step-by-step explanation:

Correct answer

Arun saved = 2/7

Geetha saved = 9/10

2/7 - 9/10

LCM of 7 and 10 is 70

2/7 = 2 × 10 / 7 × 10

= 20/70

and

9/10 = 9 × 7 / 10 × 7

= 63/70

So Geetha saved more by 20/70
