171. There are 3 trucks A,B and C. A loads at the rate of 10kg/min and B loads at the rate of 13 1/3 kg/min. C unloads at the rate of 5kg/min. If all the 3 trucks are acting simultaneously, find the time taken to load 2.4 tonnes.
Answer: Option B
Explanation:A loads in 1 min = 10 kg.
B loads in 1 min = 13 1/3 kg = 40/3 kg.
C unloads in 1 min = 5kg.
So 10+ 40/3 -5 = 55/3
Hence 1 kg loaded by A,B and C together = 3/55 min
So for 2.4 tonnes to be loaded = 2.4 *1000* 3/55 =130.9 min

172. Apples cost L rupees per kilogram for the first 30 kilograms and Q per kilogram for each additional kilogram. If the price paid for 33 kilograms of Apples is Rs.1167 and for 36 kilograms of apples if Rs.1284, then the cost of the first 10 kgs of apples is:
Answer: Option B
Explanation:30L + 3Q = 1167
30L + 6Q = 1284
Solving we get Q = 39, L = 35
So cost of first 10 kgs of apples = 35 * 10 = 350

174. Three dice are rolled. What is the probability that you will get the sum of the numbers as 10?
Answer: Option A
Explanation:Total events = 6*6*6=216
possible cases for sum equal to 10 are
(1,3,6)-6 combinations + (1,4,5)-6 combinations + (2,3,5)-6 combinations + (2,4,4)-3 combinations + (3,3,4)-3 combinations +
(2,2,6)-3 combinations
So, Total combinations = 27
Hence probability = 27/216

Answer: Option A
Explanation:when divided by 5, quotient is 11 and remainder is zero.
when 11 is divided by 2, quotient is 5 and remainder is 1.
when 5 is divided by three, quotient is 1 and remainder is 2.
when same operation is applied on 55 i.e. successively divided by 2,3,5..
we get remainders as 1,0,4 successively.

179. A can complete a piece of work in 8 hours, B can complete in 10 hours and C in 12 hours. If A,B, C start the work together but A laves after 2 hours. Find the time taken by B and C to complete the remaining work.
Answer: Option A
Explanation:A,B,C 1 hour work is=1/8+1/10+12= 37/120
A,B,C work together for 2 hours, so,A,B,C 2 hours work is: (37/120)*2=37/60
remaining work=1-37/60=23/60 (23/60 work is done by B and C together)
B,C 1 hour work is= 1/10+1/12=11/60
23/60 hours work done by B,C= (11/60)* (60/23)=11/23
So B & C and complete the remaining work = 2 1/11 days.
