Karan and Varun started running in a straight line at 5 m/s and 7.5 m/s respectively. If Karan started 90 meters ahead of Varun, how much time will Varun take to catch Karan?
ATQ,
Relative speed of Varun with respect to Karan = 7.5 − 5 = 2.5 m/s Required time = 90/2.5 = 36 seconds
36.76 + 2894.713 + 34965.11 =?
3% of 842 ÷ 2% of 421 = ?
Find the HCF of 15x2 + 8x – 12, 3x² + x – 2, 3x² - 2x, 9x² - 12x + 4
60 = (? x 10 + 250)/5
779 + 136 – 334 = 270 + 121 + ?
40% of 220 × 15 ÷ 20 = ?
1024 ÷ 32 = 2(1/2)×?
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 175
(12% of 1250 + 85% of 400) x 10 = ?2
