Question
The total age of A, B and C eight years hence will be 98
years. Find the age of C three years hence, if the present age of A and B is 30 years and 25 years respectively.Solution
Sum of present age of A, B and C = 98 β (8 Γ 3) = 74 years Present age of C = 74 β (30 + 25) = 19 years 3 years hence, age of C = 19 + 3 = 22 years
15.99% of 549.99 Γ· 11.17 = ? Γ· 20.15
74.91% of 639.95 β 599.98% of 45 + 119.987 = ?
