Question

Sahil and Arman are brothers and have Rs.60 and Rs.120 respectively. Sahil saves Rs.7 per day and Arman
saves Rs.5 per day. In how many days will Sahil and Arman save the same amount of money?​

Answer 1

Answer:

In 30 days, Sahil and Arman will save the same amount of money.

Step-by-step explanation:

Let the number of days be x.

60 + 7x = 120 + 5x

=> 7x - 5x = 120 - 60

=> 2x = 60

=> x = 30

Verify:

In case of Sahil, in 30 days he will save 7*30 = 210 and he already has 60. So his total will be 270.

In case of Arman, in 30 days he will save 5*30 = 150 and he already has 120. So his total will be 270.

Therefore, in 30 days they will save the same amount.
