Question
The ratio of age of βBβ after 6 years from now and
age of βCβ 4 years ago from now is 7:4, respectively. The present age of βCβ is 40% of the present age of βAβ. If present age of βAβ is 50 years then find the present age of βBβ.Solution
Present age of βCβ = 0.4 Γ 50 = 20 years 4 years ago from now, age of βCβ = 20 β 4 = 16 years 6 years hence from now, age of βBβ = 16 Γ (7/4) = 28 years Present age of βBβ = 28 β 6 = 22 years
116 x (2/3)% of 420 + 666 x (2/3)% of 186 = 457 x (1/7)% of 126 + 555 x (5/9)% of 198 + ?
108² + 99 X 98² =?
...2945 – 1508 + 3454 = ? + 2255
15 * 12 + 35% of 80 + 70% of 130 = ?
What will come in the place of question mark (?) in the given expression?
65% of 900 - 45% of 600 = ? X 3Β
β225 + 27 Γ 10 + ? = 320
46% of 13/92 × 24/91 × 3500 =?
What is 12% of 4% of 7% of 2 x 106 ?
- What will come in place of (?), in the given expression.
125% of 96 + 33% of 300 = ?
