Question
The ratio between the present age of Beena and Meenal is
4:7, where Sumit is 6 years younger than Meenal then find the ratio of their ages 8 years hence.Solution
Let present age of Beena be 4x years and of Meenal of 7x years. According to the question, => 4x = 7x – 6 => x = 2 Present age of Beena = 4 × 2 = 8 years Present age of Meenal = 7 × 2 = 14 years Now, 8 years hence their ratio of ages, Beena age = 8 + 8 = 16 years Meenal age = 14 + 8 = 22 years Required ratio = 16:22 = 8:11

436 × 794 – 68210 =? + 85730
520% of 360 – 12% of 400 = ? x 4
236.23 - 653.23 + 696.23 = ?
{(? × 15) + (? × 45)} – 120 = 360
What will come in the place of question mark (?) in the given expression?
(437 + ? - 167) x 2.5 = 875800 + 900 X (3)-2 - ? = 25 X 60 ÷ 2Â
37% of 810 – 32% of 460.5 = ?
- What will come in place of (?) in the given expression.
(⅗ of 450) – (⅖ of 300) = ? 1024 ÷ 16 + 800 ÷ √64 + ? = 200 * 2
