Let the father's age be x years and the son's age be (50 - x) years. In 5 years, the father's age will be x + 5 and the son's age will be (50 - x) + 5 = 55 - x. According to the condition: x + 5 = 2(55 - x) x + 5 = 110 - 2x 3x = 105 x = 35 years (father), son = 50 - 35 = 15 years. Answer: c) Father: 35, Son: 15.
?% of (150.31 ÷ 14.97 × 50.011) = 319.98
180.25 × 14.995 ÷ √26 = ? × 5.985
56.02% of 1499.98 + 64.04% of 2501.01 = ? + 25.05 × 49.98 + 6.063
12.99 × 9.99 + ? × 7 + 240.001 = 21.012
20.02% of (95.96 × 104.01 – 56.02 × 64.04) – ? = 12.02 × 39.96 + 103.03
74.99 x 175.01 - 75.12 x 154.98 + + 39.98) x 3.98 = (785.01 + 265.01) x 1.99
59.98% of 3200 + 50.28% of 2800 = 89.99% of 2800 + ?
(14.56)² × √840 =?
...? = 41.92% of 49.96% of (45.07 1.97 – 4.98 2.03 )
