Question
10 years ago from now, ratio of ages of βRβ and
βLβ was 3:8, respectively. If βLβ is 6 years elder to βRβ, then what will be the age of βLβ, 6 years hence from now?Solution
10 years ago from now, let ages of βRβ and βLβ be β3xβ years and β8xβ years, respectively. So, 8x β 3x = 10 Or, 5x = 10 Or, x = 2 Present age of βLβ = 8x + 6 = 8 Γ 2 + 6 = 22 years Age of βLβ, six years hence from now = 22 + 6 = 28 years
7/11 × 1034 + 1(4/7) × 2401 = 1230 +?
140% of 9/8 of ? = 108% of 2800
4.56 + 56.4 + 64.5 = ? + 10.46
- What will come in the place of question mark (?) in the given expression?
?Β² = 28% of 35% of 4500 12.5% of (100 + ?) = 40
What will come in the place of question mark (?) in the given expression?
? = 12.5% of 25% of 20% of 1280 + 1248
(? + 180 + 13 Γ 6) Γ· 20 + 3.5 Γ 512 (1/3) = 82
Solve for the ?
What will come in the place of question mark (?) in the given expression?
(437 + ? - 167) x 2.5 = 875(22% of 1500 + 15% of 2200) = ? x 11
