The present ages of Lewis and Brown is 1:2. Three years from now their ages be in ratio 3:5. Find the age of Brown after 5years?

Let

Brown=b

Lewis=l

Present ages be b/l=1:2

2l-b=0....eq(1)

After three years l+3/b+3=3:5

5l-3b=6

By resolving eq

b=12

l=6

After 5 years l= 11

b=17

The average of 4 quantities is 5. The average of 2 them is 6. What is the average of the remaining two numbers?

The average of 4 quantities is 5.

Therefore,the sum of the 4 quantities is 4 Ã— 5 =20.

The average of two of these 4 quantities is 6.

Therefore, the sum of these three quantities = 2 Ã— 6 = 12

The sum of the remaining two quantities = 20 - 12 = 8.

Average of these two quantities = 8 / 2 = 4.
