B. 1/2.5
C. 1903/2156
D. 4/9
A. 60 gallons
B. 100 gallons
C. 120 gallons
D. 180 gallons
Explanation:
Work done by the waste pipe in 1 minute = 1/15 – (1/20 + 1/24) = – 1/40
Volume of 1/40 part = 3 gallons
Volume of whole = 3 * 40 = 120 gallons.
A. 14.4 minutes
B. 20 minutes
C. 28.8 minutes
D. 32 minutes
(2/3)*24=16 miles Time taken to cover the first 16 miles
= (16/40) hours
= 24 minutes Time taken to cover the next 8 miles
= (8/60) hours
= 8 minutes Time taken for the entire journey
= 32 minutes
A. Rs. 10,500, Rs. 13,500, Rs. 16,500
B. Rs. 11,500, Rs. 13,000, Rs. 16,000
C. Rs. 11,000, Rs. 14,000, Rs. 15,500
D. Rs. 11,500, Rs. 12,500, Rs. 16,500
Explanation:
A:B:C = 35000 : 45000 : 55000 = 7:9:11
A’s = 40500 * 7/27 = Rs. 10500
B’s = 40500 * 9/27 = Rs. 13500
C’s = 40500 * 11/27 = Rs. 16500

Percentage of failure = (100 – 65) % = 35 %
Let the total number of examinees be x.
Then 35 % of x = 420
=> 35/100 × x = 420
=> x =(420 × 100/35) = 1200
