The present age of lewis and Brown are in ratio 1:2. Three years from now, the ages will in ratio 3:5. Find the age of lewis after five years?

Let's present age

Lewis =l

Brown=b

l/b=1:2

l-2b=0

After three years

l+3/b+3=3:5

5l-3b=6

l=6

b=12

After 5 years

l=11

b=17

In following alphabet series , one term missing as shown by question mark . Choose missing term from options.

Z, Y, X, U, T, S, P, O, N, K, ?, ?

The given series consists of three consecutive letters from the end, then two letters skipped, then again three consecutive letters from the end so on..

Find the wrong number in the series:

7, 28, 63, 124, 215, 342, 511

7, 28, 63, 124, 215, 342, 511

Clearly, the correct sequence is

(23 - 1), (33 - 1), (43 - 1), (53 - 1), (63 - 1), (73 - 1), (83 - 1).

So 28 is wrong and should be replaced by (33 - 1) i.e. 26.

Hence, the answer is (B)..
