Question Number 8 Exercise 3E of RS Aggarwal Solution

Here the quotient and remainder of the n time of larger and n time of smaller of two numbers is given. you have

to find the numbers.

# If three times the larger of two numbers is divided by the smaller, we get 4 as the quotient and 8 as the remainder. If five times the smaller is divided by the larger, we get 3 as the quotient and 5 as the remainder. find the numbers.

Let the larger number be x and the smaller number be y.Given that 3 times, the larger number is divided by smaller we get 4 as Quotient and 8 as remainder.= > 3x = y * 4 + 8= > 3x = 4y + 8= > 3x – 4y = 8 ——— (1)Given that if five times the smaller is divided by larger we get 3 as Quotient and 5 as remainder.= > 5y = 3x + 5= > 5y – 3x = 5= > -3x + 5y = 5 ——— (2)On solving (1) & (2), we get= > 3x – 4y = 8= > -3x + 5y = 5——————–y = 13Substitute y = 13 in (1), we get= > 3x – 4y = 8= > 3x – 4(13) = 8= > 3x – 52 = 8= > 3x = 52 + 8= > 3x = 60= > x = 60/3= > x = 20.Therefore the numbers are 20, 13.
