Question
Find the distance traveled by a train moving at a speed
of 90 km/h, which takes 20% less time than a truck that covers 630 km at a speed of 70 km/h.Solution
Time taken by the truck = distance/speed = 630/70 = 9 hours Time taken by train = 80% of 9 = 7.2 hours Distance covered by train = 90×7.2 = 648 km Distance from A to B = 4320/2 = 2160 m = 2.16 km
{(23.65 × 35.12) ÷ 6.97} + 179.86 = ? × 14.76
Find the approximate value of Question mark(?). No need to find the exact value.
(34.95 × 7.03) ÷ 5 + 27.98% of 249.88 – √(80.81) = ?
...What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
9.89 x 4.99 + 2.01 x 49.89 = ?% of 299.69
What approximate value will replace the question mark (?) in the following?
29.99...
What will be the approximate value of the following questions.
(74.75% of 600.29 – 44.85% of 399.99) × (√224.95 ÷ 15.01) = ?
( 1000)1/3  × 10.11 × 4.97 ÷ 10.32 =? – 15.022
12.03 x 4.21 +19.95% of 300.05 =Â ?
79.79% of 299.87 - 54.67% of (39.982 - 9.822 ) = ? - 19.92 × 199.98
