Question

age A year more than B is the same of same of there age is 45 year find the age of both ?​

Answer 1

45=A+B

A=3,B=5 value

A= 45 /3 ,15×3= 45

B = 45/5 ,5×9 = 45

since we find age of A and B

Answer 2

Answer:

Let the members be Old Having age O + other 9 having ages x and New one having age Y

Sum of their ages = (Y + 9 × x) and average = (Y + 9 × x)/10

Before 4 years sum was (O + 9 x – 10 × 4) and average = (O + 9 x – 10 × 4) /10

equating, Y + 9 x = O + 9x – 40

Y = O – 40

Younger is 40 years younger than Old
