Question
The average age of 4 children in a family is 30% of the
average age of the mother and the youngest child. The total age of the father and the eldest child is 42 years. If the father’s age is 28 years, what is the age of second eldest child?Solution
Since the total or average age of all the family members are not given, the given data is inadequate. So, the age of second eldest child cannot be determined.
(`sqrt(224.95)` `xx` `sqrt(440.89)` ) + (`sqrt(783.82)` `xx` `sqrt(440.87)` ) = ? + 150.03% of 120.33 - 139.86% of 1249.88
...If cosec (2A + B) = (2/√3) and cosec (A + B) = √2, find the value of (4A - B) .
79.79% of 299.87 - 54.67% of (39.982 - 9.822 ) = ? - 19.92 × 199.98
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
(4096)1/3 × 10.11 × 11.97 ÷ 24.32 = ? + 15.022
179.89 + 17.04² + ?³ = √783.97 * 29.09
124.88% of 1199.85 + 99.99 ÷ 3.99 = ?
What approximate value will replace the question mark (?) in the following?
? –...
3 √2197.08 × 5.15 + 13.302 = √675.99 + ?
(29.98% of 9840) + ? + (19.899% of 8490) = 7560
