Question
A car can finish a certain journey in 10 hours at a
speed of 42 kmph. In order to cover the same distance in 7 hours, the speed of the car (km/h) must be increased bySolution
speed = (distance/time) distance = speed time = 10 × 42 = 420 km to cover the same distance in 7 hours speed = 420/7 = 60 Km/h increase in speed = 60 -42 =18 km/h
20.05% of 220.05 – 15.15% of 99.99 × 2.02 = ?
The income of a person is Rs.15000 and his expenditure is Rs.12000. In the next year his income and expenditure is increased by 8% and 13% respectively....
6269 + 0.25 × 444 + 0.8 × 200 = ? × 15
...25.6% of 250 + √? = 119    Â
15% of 5000 - √900 = ? + 10% of 1800
72 + 122 - 25% of 600 = ?
[∛(3375/19683  )- ∛(125/1728  )  ] ÷ ∛(64/729)  = ? - 3/8Â
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2Â
(3984 ÷ 24) x (5862 ÷ 40) = ?
√10201 × √3969 - (52)² = √? + (60)²
