Answer» Question :-- A SUM of money was divided between Rajeev and Ashish so that Rajeev gets 7/19 of the whole account. If he gets 5600, how MUCH was the total sum. ? ✪ ANSWER :- Let the Total sum was Rs.x . it is given that, Rajeev got 7/19 of Total. ➳ That MEANS Rajeev gets = 7/19 of x = (7X)/19 . Now, it is given that, Rajeev gets Rs.5600 . So, ➪ (7x)/19 = 5600 ➪ 7x = 5600 * 19 Dividing both sides by 7, ➪ x = 800 * 19 ➪ x = Rs. 15200 Hence, Total sum was Rs.15200.

Answer»

Question :-- A SUM of money was divided between Rajeev and Ashish so that Rajeev gets 7/19 of the whole account. If he gets 5600, how MUCH was the total sum. ?

✪ ANSWER :-

Let the Total sum was Rs.x .

it is given that, Rajeev got 7/19 of Total.

➳ That MEANS Rajeev gets = 7/19 of x = (7X)/19 .

Now, it is given that, Rajeev gets Rs.5600 .

So,

➪ (7x)/19 = 5600

➪ 7x = 5600 * 19

Dividing both sides by 7,

➪ x = 800 * 19

➪ x = Rs. 15200

Hence, Total sum was Rs.15200.
