Answer : From the first statement If any number is divisible by 3, its square is always divisible by 9. So we cannot find the number from the given statement. From second statement 40% of the number is 2/5th of that number. So the question cannot be answered even after using both statements together.

6.  The ratio of ducks and frogs in a pond is 37: 39 respectively. The average number of ducks and frogs in the pond is 152. What is the number of frogs in the pond?

148

152

156

144

None of these

Answer : Let number of ducks = 37x And number of frogs = 39x Average = 38x = 152 x = 4. Hence number of frogs = 39x = 156

7.  P and Q are two taps which can fill a tank individually in 5 minutes and 10 minutes respectively. However, there is a leakage at the bottom which can empty a filled tank in 15 minutes. If the tank is empty initially, how much time will both the taps take to fill the tank (leakage is still there)? 

4(2/7)min

3(5/7)min

5 min

2 min

None of these

Answer :Let the capacity of the tank is 30 litres. P can fill 6 litres in one min. Q can fill 3 litres in one min. C can empty 2 litre in one min Together both the pipes and leakage will fill 7 litres in one min. Hence time to fill the tank = 30/7 mins

8.  What approximate amount of compound interest can be obtained on an amount of Rs. 1950 at the rate of 6% p.a. at the end of 3 years?

Rs. 347.4

Rs. 384

Rs. 344

Rs. 372.5

Rs. 368.5

Answer :P = 1950, R = 6%, N = 3 years 1st year interest = 117 2nd year interest = 117 + 7.02 3rd year interest = 117 + 7.02 + 7.02 + 0.4212 Total interest = 372.5 (approx)
