Let the present ages of 'A' and 'B' be '3x' years and '5x' years, respectively. ATQ; (5x + 8) = 3 x (3x - 2) Or, 5x + 8 = 9x - 6 Or, 4x = 14 x = 3.5 So, present age of 'A' = 3 x 3.5 = 10.5 years
12 × 6 + 24 – 36 of 5 + 160 = ?
√1444 + √729 – √2116 = ?
I. 8x² - 74x + 165 = 0
II. 15y² - 38y + 24 = 0
180 ÷ 3 of 2 = 102 – ?
2850 ÷ 2.5 - ? × 42 = 300
4261 + 8234 + 2913 + 8217 + 6283 + 4172 =?
72 + 122 - 25% of 600 = ?
