Answer:
35 and 7
Explanation:
Let the two numbers be x and y
given one number is 5 times the another number
⇒ x = 5y ___________(1)
if 21 is added on both numbers one number is twice the other
⇒x + 21 = 2( y + 21)
⇒ 5y + 21 = 2y + 42 [∵ x = 5y]
⇒ 3y = 21
∴ y = 7
from (1)
⇒ x = 5y = 5(7) = 35
∴ x = 35
