The ratio of the present ages of puneet and Appu is 2 : 3. After 3 years the ratio of their ages will be 3 : 4. The present age of Puneet is:

Annual incomes of A and B are in the ratio 4 : 3 and their annual expenses are in the ratio 3 : 2. If each of them saves Rs. 600 at the end of the year, what is the annual income of A?
The average of marks in Mathematics for 5 students was found to be 50. Later, it was discovered that in the case of one student the marks 48 were misread as 84. The correct average is:
Out – 84
In  48
Diff = 36
= 42.8
If the cost price of 10 articles is equal to the selling price of 7 articles, then the gain or loss per cent is:
C.P (10) = S.P (7)
Two bicycles were sold for Rs. 3990 each, gaining 5% on one and losing 5% on other. The gain or loss per cent on the whole transaction is:
Two trains are running with speeds 30 km/hr and 58 km/hr in the same direction. A man in the slower train passes the faster train in 18 seconds. The length (in metres) of the faster train is:
So, L = 140 m
In a school 40% of the students play football and 50% play cricket. If 18% of the students neither play football nor cricket, the percentage of the students playing both is:
F + C = 90%
But, 100%  18% = 82%
So, Diff = 90%  82% = 8%
If the side of a square is increased by 25%, then its area is increased by:
A student has to secure 40% marks to pass. He gets 90 marks and fails by 10 marks. Maximum marks are:
If A’s height is 10% more than B’s height, by how much per cent less is B’s height than that of A?
A reduction of 20% in the price of sugar enables a purchaser to obtain 3 kg more for Rs. 120. The original price (per kg) of sugar is:
Reduction = 20%

So, original price = 120/12 = 10
If the difference between the simple and compound interests on a sum of money for 2 years at 4% per annum is Rs. 80, the sum is:
A number, when divided by 119, leaves a remainder of 19. If it is divided by 17, it will leave a remainder of:
The L.C.M. of two numbers is 20 times their H.C.F. The sum of H.C.F. and L.C.M. is 2520. If one of the numbers is 480, the other number is:
L x H = a x b
20 H x H = 480 x b
L + H = 2520
So, b = 600
The number, whose square is equal to the difference between the squares of 975 and 585, is:
x^{2} = (975)^{2} – (585)^{2}
x^{2} = 608400
So, x = 780
A tap can fill a cistern in 8 hours and another tap can empty it in 16 hours. If both the taps are open, the time (in hours) taken to fill the tank will be:
Out of 10 teachers of a school, one teachers retires and in his place a new teacher of age 25 years joins. As a result of it, the average age of the teachers is reduced by 3 years. The age of the retired teacher is
