Question 1 of 50
1. Question
Mahesh marks an article 15% above the cost price of Rs. 540. What must be his discount percentage if he sells it at Rs. 496.80?
Correct
CP = Rs. 540, MP = 540 + 15% of 540 = Rs. 621
SP = Rs. 496.80, Discount = 621 – 496.80 = 124.20
Discount % = 124.2/621 * 100 = 20%Incorrect
CP = Rs. 540, MP = 540 + 15% of 540 = Rs. 621
SP = Rs. 496.80, Discount = 621 – 496.80 = 124.20
Discount % = 124.2/621 * 100 = 20%

9. Question
Train P crosses a pole in 30 seconds and train Q crosses the same pole in one minute and 15 seconds. The length of train P is threefourths the length of train Q. What is the ratio of the speed of train P to that of train Q?
Correct
Given that train P crosses a pole in 30 seconds and train Q crosses the same pole in one minute and 15 seconds.
Let the length of train P be L_{P} and that of train Q be L_{Q}
given that L_{P} = 3/4 L_{Q}
As the train P and Q crosses the pole in 30 seconds and 75 seconds respectively,
=> Speed of train P = V_{P} = L_{P}/30
Speed of train Q = V_{Q} = L_{Q}/75
L_{P} = 3/4 L_{Q}
=> V_{P} = 3/4 L_{Q}/(30) = L_{Q}/40
Ratio of their speeds = V_{P} : V_{Q}
= L_{Q}/40 : L_{Q}/75 => 1/40 : 1/75 = 15 : 8Incorrect

If p, q and r are positive integers and satisfy x = (p + q – r)/r = (p – q + r)/q = (q + r – p)/p, then the value of x is?
Correct
Hence, x = (p + q – r)/r = (p – q + r)/q = (q + r – p)/p
=> x = (p + q – r + p – q + r + q + r – p)/(r + q + p)
=> x = (p + q + r)/(r + q + p) = 1.Incorrect
Hence, x = (p + q – r)/r = (p – q + r)/q = (q + r – p)/p
=> x = (p + q – r + p – q + r + q + r – p)/(r + q + p)
=> x = (p + q + r)/(r + q + p) = 1.
