Question
The ratio of the speed of two bus P and Q is 4 :7. If P
takes 180 minutes more than Q to cover a certain distance, the find then actual time taken by Q to cover the same distance.Solution
Ratio of speed = 4 : 7 Ratio of time = 7 : 4 Now, 7 – 4 = 180 3 = 180 1=60 Q=4=60*4=240 minutes (4 hrs)
(22.5 × 24) ÷ 40 + 51.50 = ? ÷ 5.25
What will come in the place of question mark (?) in the given expression?
59.92 × 15.11 + √4224 = ? + 144.9Â
What will come in the place of question mark (?) in the given expression?
30% of 520 + 16% of 1500 = ? + 244
276 ÷ 11.5 + 12 = ? x 3
3/7 Of 504 ÷ 12 + 17 = √?
12% of 10% of 15% of 5000 + (12 x 15) = ?

Simplify the following expression:
(164-1)/17×15× (28+1)
(160 × 12 - 13 × 20)/(120 × 2 + 2 × 35 + 2 × 11) = ?
