Ratio of present ages of A and B is 5:7, respectively. C who is 3 years older than A will become 30 years older after 12 years. Find the present age of B.
Let, present ages of A and B be ‘5x’ years and ‘7x’ years respectively. So, 5x + 7 = 30 – 12 5x = 15 x = 3 Present age of B = 7x = 21 years
2222 ÷ 22 + 992 ÷ 16 + 650 ÷ 25 = ?
30% of 8/5 × 5/7 × 2870 =?
(-251 × 21 × -12) ÷ ? = 158.13
464 + 181 +? = (154 × 25) - (15) 2
2852 + 7848 + 2962 + 4268 = ? – 1460
168 163 153 138 118 ?
...√256 × 25 – 15 × 14 =?
7/11 × 1034 + 1(4/7) × 2401 = 1230 +?
60% of 60 + 40% of ? = 75% of 160 - 30% of 120
