Q:

The minute hand of a clock overtakes the hour hand at intervals of 65 minutes of the correct time. How much a day does the clock gain or lose?

A) (10 + 10/143 )min B) (10 + 1/143 ) min
C) (10 + 20/143 ) min D) (10 + 30/143) min
 
Answer & Explanation Answer: A) (10 + 10/143 )min

Explanation:

In a correct clock, the minute hand gains 55 min. spaces over the hour hand in 60 minutes.

To be together again, the minute hand must gain 60 minutes over the hour hand.

55 minutes are gained in 60 min.

60 min. are gained in [(60/55) * 60] min = min.

But they are together after 65 min.

Therefore, gain in 65 minutes =  = min.

Gain in 24 hours =  = 1440/143 min.

Therefore, the clock gains (10 + 10/143 )minutes in 24 hours.

A) 11pm B) 12pm
C) 1pm D) 2pm

Now 23 hrs 44 min. of this clock = 24 hours of correct clock.

356/15 hrs of this clock = 24 hours of correct clock

89 hrs of this clock = (24 x 31556 x 89) hrs of correct clock.

So, the correct time is 11 p.m.

Q:

A sum of money amounts to Rs.6690 after 3 years and to Rs.10,035 after 6 years on compound interest.find the sum.

A) 4360 B) 4460
C) 4560 D) 4660
 
Answer & Explanation Answer: B) 4460

Explanation:

Let the sum be Rs.P.then
P(1+R/100)^3=6690…(i) and P(1+R/100)^6=10035…(ii)
On dividing,we get (1+R/100)^3=10025/6690=3/2.
Substituting this value in (i),we get:
P*(3/2)=6690 or P=(6690*2/3)=4460
Hence,the sum is rs.4460.
