ATQ, Statement I: Length of train Q = 36 × 10 = 360 metres We cannot Find the speed of train P. So, data in statement I alone is not suicient to answer the question. Statement II: We cannot ind the speed of trains P and Q. So, data in statement II alone is not sufficient to answer the question. Combining Statements I and II: Length of train Q = 360 metre Let the speed of train P be 'a' m/sec Length of train P = 35a meters Train P crosses train Q in 55 sec when travelling in same direction. So,a – 36 = (360 + 35a)/55 Or, 55a – 1980 = 360 + 35a Or, a = 117 Length of train P = 35 × 117 = 4095 metres So, the data in both statements I and II together are necessary to answer the question.
3.3 Times 2/27 of 40% of 364=?
√14400 x √8100 - (60)² = ? + (80)²
325934.78 + 78545.30 + 92.25 =?
(22% of 1500 + 15% of 2200) = ? x 11
125 ÷ 5 + 14 × 4 = ? + 72 ÷ 4 – 35
(560 ÷ 32) × (720 ÷ 48) = ?
154 × 7 + 480 × 5 = ?% of 6956
14 × 11 + 25 – ? = 21% of 300
√49 + √144% of 3600 = ?
(15 × 16) + 242= ? × 16
