Question
βAβ is 8 years younger than βBβ and 7 years
elder than βCβ. If the present age of βBβ and βDβ is 20 years and 15 years, respectively, then find the ratio of present age of βCβ to present age of βDβ.Solution
Present age of βAβ = 20 β 8 = 12 years Present age of βCβ = 12 β 7 = 5 years Required ratio = 5:15 = 1:3
[(120)2 ÷24 ×25] ÷ 250 =?
What should come in place of the question mark (?) in the following question?
2 β [6 β {3 + (β4 + 5 + 1) Γ 8} + 12] = ?
140% of 1270 + 60% of 2085 = 1881 + β?β% of 287
15 Γ 18 + 25 Γ 12 + 30 Γ 24 = ?% of 1720
Evaluate:
β729 + β49 - β16 + 1/β64
Simplify the following expression.
(3-3 Γ 3 + 3 Γ· 3 + 3 Γ 5) Γ 2 of 5 + (2 + 2 Γ· 2 + 2 Γ 2 - 2)
15.8% of 9000 + 20.4% of 7500 = 30% of ?
2856 ÷ 34 = ?% of 240
(3984 ÷ 24) x (5862 ÷ 40) = ?
