Five years ago the ratio of Krishna’s age to his father’s age was 1:4 and five years from now their ages will be in the ratio 2:5 What is the ratio of their present ages ?
The ratio of ages of Krishna and his father 5 years ago was = 1:4
So, let their ages be x and 4x
Five years later their ages are x+10: 4x + 10
But that is in the ratio of 2 : 5
So, 5x + 50 = 8x + 20
So, x = 10
Their ages now = 15:45 = 1:3
If Anil’s salary is onethird more than that of Sunil’s then by what percentage Sunil’s salary is lesser than Anil’s ?

A certain amount which was loaned on simple interest doubled in 10 years Then the amount received is loaned on compound interest for another 2 years on the same rate What is the total rise in the amount after 12 years with the initial principal amount ?
The amount doubled in 10 years. So, the interest = principle.
So, rt/100 = 1
r = 10% pa
Now compound interest = ?
2P(1 + 1.1)^{2} = 2P x 1.21 = 2.42P
Total rise is P to 2.42P = rise of 142%
Length and breadth of a rectangle are in the ratio 3:4 while the perimeter of it is 56 cm.What is the area of the rectangle ?
The length and breadth are in the ratio 3:4
Let them be 3x and 4x respectively.

So, 2(7x) = 56
So, x = 4
Area = 3x * 4x = 3*4*4*4 = 192 sq cms
A person used to get 15 litres of petrol for a certain amount but due to the hike in the price he is getting one litre less for the same amount What is the percentage rise in the petrol price ?
Let the amount that is fixed be 210 Rupees
He used to get 15 litres of petrol for Rs. 210 earlier and then only 14 litres.
Initial cost of petrol = 210/15 = 14 Rs
Final cost of petrol = 210/14 = 15 Rs.
% rise in petrol price = 100/14 = 7 1/7
An article costs Rs. 80 to the vendor. If he marks the article for 50% more than the cost price and sells it 25% less than the marked price, what is his gain percentage ?
Cost Price of the article = 80 Rs.
Marked Price = 80 x 1.5 = 120
Selling Price = 120 x .75 = 90
Profit = 10 Rs
Profit % = 10/80 = 12.5%
Two bikers A and B started for a race of 120 km with a constant speed of 30 kmph and 40 kmph respectively. After 2 hours A raised his speed and both reached the finish line at same time What was the speed of A after 2 hours of starting the race ?
Let A's new speed be x kmph after 2 hours. Total time taken by B = 120/ 40 = 3 hours.
Total distance travelled by A in 2 hours = 30 x 2 = 60 kms
So,
A should travel 60 kms in the last one hour. He can do that if he travels at 60 kmph.
The inlet to a tank can fill it in 4 hours while the outlet to the tank can empty it in 5 hours Both the pipes were opened at 9 Am but after sometime the outlet was closed and it is observed that the tank was full at 5 PM. At what time was the outlet closed ?
Let the outlet be open for x hours.
Let there be 100 units of water in the tank.
So, the speed of inlet is 25 units per hour and speed of the outlet is  20 units per hr.
Let them be open for x hours. So, the total tank filled is 25 x  20x =5x
For 8  x hours the inlet is open. So, units of water = (8x)*25
But that sum = 100
5x + 200  25 x = 100
20 x = 100
So, x = 5 hours. ie till 2 PM
When product of two numbers is 768 and LCM is 96 what is the HCF of these numbers ?

So, HCF = product/ LCM = 768/96 = 8
Onefourth of an amount was loaned at simple interest with 2% rate of interest and the remaining part was lent on simple interest at 3% rate of interest What is the average rate of interest for the whole amount ?
Let the amount be 100 Rs.
One fourth of it is at 2 % pa
So, 25 x 2 x 1 /100 = .5
The rest is on 3% pa interest.
So, 75 x 3 x 1 /100 = 2.25
So total interest = 2.75
Interest rate = ?
Interest rate = i x 100/ pt
= 2.75 x100/100 = 2.75%
The ratio of occupied seats to the vacant seats in a bus is 1:4 By the time the bus started some more passengers tried to enter the bus which would have made the ratio 4:1 But as they failed in the attempt they were seated in an empty bus with same capacity as the previous one.What is the ratio of occupied seats to the vacant seats in this bus ?
Let there be 100 seats in each bus. Initial ratio = 1:4
So, the initial people seated = 20
New ratio = 4:1
So, new people = 60
In the new bus, the ratio = 60 : 40 = 3:2
