Question
The ratio of A and B present age is 5:2. The product of
their ages is 9000. What will be the ratio of their ages after 3 years?Solution
Let their present age be 5x and 2x respectively. Product of their ages = 10x² = 9000 => x² = 900 => x = 30 Present age of A = 5x = 150 years Present age of B = 2x = 60 years Ratio of their ages after 3 years = (150+3) : (60+3) = 153:63 = 17:7
Evaluate: 360 Γ· [ {18 β (6Γ2)} Γ 5 ] + 72 β 33
(43)² - (28)² + (32)² = ?% of 2500
Evaluate:
β729 + β49 - β16 + 1/β64
What will come in place of (?) in the given expression.
12.5 + 7.75 - 3.6 = ?62 of 8 - 320 Γ· 4 = ?3 + 200
2(1/3) + 2(5/6) β 1(1/2) = ? β 6(1/6)
What will come in the place of question mark (?) in the given expression?
30% of 520 + 16% of 1500 = ? + 244
60% of 120 β ?% of 64 = 20% of 200
35% of 840 + 162Β = ? β 25% Γ 300
20% of 240 + 18% of 200 = ?
