Question
16 years ago from now, ratio of ages of βRβ and
βLβ was 3:5, respectively. If βLβ is 9 years elder to βRβ, then what will be the age of βLβ, 5 years hence from now?Solution
16 years ago from now, let ages of βRβ and βLβ be β3xβ years and β5xβ years, respectively. So, 5x β 3x = 16 Or, 2x = 16 Or, x = 8 Present age of βLβ = 5x + 9 = 5 Γ 8 + 9 = 49 years Age of βLβ, five years hence from now = 49 + 5 = 54 years
- Find the value of the expression:
40 + 5 β 7 Γ [16 + 9 β 3 Γ (27 β 13)] 8 Γ (25 % of 720) β 50 % of 135 % of 840 = ?
- What will be come in place of (?) in the given expressions.
(3/4 of 480) β (2/5 of 350) = ? - What will come in place of (?), in the given expression.
β2025 + 35% of 400 = ? 13/3 β (23/6) = ? β (22/9)
(1296)Β -3/4Β = ?
- What will come in the place of question mark (?) in the given expression?
?Β² = 28% of 35% of 4500 What will come in the place of question mark (?) in the given expression?
(72 Γ 6 Γ· 12) Γ 6 = ?
What will come in the place of question mark (?) in the given expression?
? = 70% of 36% of (25 Γ 320) + 150
