Question
Arjun and Bittu together covered a total distance of 150
km. Arjun travels at a speed of 75 km/hr and Bittu at 25 km/hr. The total time they spent traveling is 4.4 hours. Calculate the distance that Arjun covered.Solution
ATQ, Let the distance covered by Arjun be 'd' km. Therefore, distance covered by Bittu = (150 – d) km According to the question, d/75 + (150 – d)/25 = 4.4 Or, {d+ 3(150 – d)} × 75 = 4.4 2d = 450 – 75 × 4.4 Or, 2d = 450 – 330 Or, d = 120/2 = 60 km
?% of (168 ÷ 8 × 20) = 126
20% of 1500 – 75% of 200 = 125% of ?
Find the value of 16 X [(8 - 5) of 12 ÷ 4].
√196 + (0.25 × 144) + 19 = ? + 72
22 * 6 + 45% of 90 + 65% of 180 = ?
52% of 400 + √(?) = 60% of 600 - 25% of 400
(25 × 12 + 30 × 8 – 22 × 10) = ?
What will come in the place of question mark (?) in the given expression?
(240% of 175 ÷ √16) X 6 + 80% of 400 = ?3 + 179 + 42
What will come in the place of question mark (?) in the given expression?
(144 × 16 ÷ 12) × 6 = ?
808 ÷ (128)1/7 + 482 = 4 × ? + 846
