Question
T’s age is 2imes the age of D. 4 years ago, the
ratio of T and D is 3:1. Find the age of P who is 3/4 of T’s age. TYPE NSolution
Let D’s age be x years. Then, T’s age = 2x years According to question, => (2x – 4)/(x - 4) = 3/1 => 2x - 4 = 3x – 12 => x = 8 T’s age = 2x = 16 years P’s age = 3/4 × 16 = 12 years
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 = ?
