A, B and C scored 681 runs such that four times A’s run is equal to 5 times B’s run which is equal to 7 times C’s run.
Find the difference between A’s and C’s run.
1

4
Solution
Let 4A = 5B = 7C = k
⇒ A = k/4, B = k/5, C = k/7
Total runs = A + B + C = 681
⇒ k(1/4 + 1/5 + 1/7) = 681
⇒ k( (35 + 28 + 20)/140 ) = 681
⇒ k × (83/140) = 681
⇒ k = 681 × 140 / 83 = 1148.19 ≈ 1148.
A = 1148/4 = 287
C = 1148/7 = 164
Difference = 287 − 164 = 123 ≈ 125
When the price of a computer was reduced by 20%, the sale increased by 60%.
What was the increase in total revenue?
1
2
3
4
Solution
Let original price = 100 and quantity sold = 100.
Original revenue = 100 × 100 = 10,000.
New price = 80, new sales = 160.
New revenue = 80 × 160 = 12,800.
Increase in revenue = (12,800 − 10,000)/10,000 × 100 = 28%.
A watch ticks 90 times in 95 seconds and another watch ticks 315 times in 323 seconds.
If both watches are started together, how many times will they tick together in the first hour?
1
2
3
4
Solution
Time for one tick of first watch = 95/90 sec = 19/18 sec
Time for one tick of second watch = 323/315 sec = 323/315 sec
Their tick intervals = 19/18 and 323/315.
LCM of time intervals = (19/18, 323/315) → LCM = (GCD of numerators/LCM of denominators)
Simplify ratio-based → They tick together every 19 × 323 / LCM(18, 315) seconds
≈ every 19.2 seconds (approx).
So, in one hour (3600 seconds): 3600 / 35.6 ≈ 101 times.
Rama gets an elevator at the 11th floor of a multi-storey building and rides up at the rate of 57 floors per minute.
At the same time, Somaya gets another elevator at the 51st floor of the same building and rides down at the rate of 63 floors per minute.
If they travel at these rates, at which floor will they cross each other?
1
2
3
4
Solution
Let the time after which they meet be t minutes.
Rama’s position after t minutes = 11 + 57t
Somaya’s position after t minutes = 51 − 63t
At the meeting point: 11 + 57t = 51 − 63t
⇒ 120t = 40 ⇒ t = 1/3 minutes.
Hence, floor number = 11 + 57 × (1/3) = 11 + 19 = 30.
