Question
When the average age of a husband and wife and their son
was 44 years, the son got married and a child was born just one year after their marriage. When child turned to be 7 years, then the average age of the family become 38 years. What was the age of daughter-in-law at the time of marriage?Solution
At the time of son’s marriage, (Husband + Wife + Son) = 44 × 3 = 132 years and Let the age of daughter-in-law be x years Eight years after marriage, 132 + (8 × 3) + 7 + x + 8 = 190 132 + 24 + 7 + x + 8 = 190 x = 19 years
Determine the value of k such that the points A(2,3), B(4,k), and C(6,-3) lie on the same straight line.
Solve the given equation for ?. Find the approximate value.
(3/5 of 399.78 + 7/9 of 360.15) ÷ (√63.94 + 25% of 383.94) = ?
...[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )Â
65.22 of 359.98% + 459.99 ÷ 23.18 = ?
{(23.65 × 35.12) ÷ 6.97} + 179.86 = ? × 14.76
