Total age of three children = 14 × 3 = 42 years Let their ages be x, 2x and 3x respectively. => x + 2x + 3x = 42 => 6x = 42 => x = 7 Therefore the age of youngest child = 7 × 1 = 7 years
Find the simplified value of the given expression
30% of 215 + 135% of ? = 469.5
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
9/5 × 18/25 ÷ 42/21 = ? - 82/75
89 ÷ 512 × (1/64) = (23)?
If A = 0.84181818... then what will be the difference between the numerator and denominator of the lowest fraction form of A?
35% of 240 – 6 2 = ? 2 – √256
Simplify: (1 ÷ 0.08)
