Question
The respective ages of a mother and her daughter are 30
and 8 years. In how many years will the mother be thrice as old as her daughter?Solution
Mother’s age = 30 years Daughter’s age = 8 years Let after ‘t’ years, mother’s age is thrice of her daughter. => 30 + t = 3(8 + t) => 30 + t = 24 + 3t => 2t = 6 => t = 3 yrs
((67)32 × (67)-18 / ? = (67)⁸
What will come in the place of question mark (?) in the given expression?
?% of (112 X 3 + 164) + 75 = 2 X 140 + 35
20% of 450 - 15% of 400 = 25% of ?
√121 + √961− √289 =?2
45% of 1020 + ?% of 960 = 747

(〖(0.4)〗^(1/3) × 〖(1/64)〗^(1/4) × 〖16〗^(1/6) × 〖(0.256)〗^(2/3))/(〖(0.16)〗^(2/3) × 4^(-1/2) ×〖1024〗^(-1/4) ) = ?
(512) (2/3) × √64 ÷ (512) (1/3) = (64) (?/2) ÷ (2)6
1231 + 1312 + 2113 – 3211 = ?
Simplify the following expression:-
