Ten years ago X was half of Y. If the ratio of their present ages is , what will be the total of their present ages?
EditExplanation
- Let the present age of X is x years and Y is y years.
- Before 10 years, X was half of Y, i.e..
- Ratio of their present ages is , i.e..
- Solving both the equations,
x = 15 and y = 20
- We are asked to find the total of their present ages.

Question 8
Write in Short Short Answer▾
If the word ‘ddosszm’ is changed to ‘central’ then what will be the change for ‘rtjbl’ ?
EditExplanation
Here, ddosszm = central
d = c, i.e.. first letter is decremented by 1 position
d = e, i.e.. second letter is incremented by 1 position
o = n, i.e.. third letter is decremented by 1 position
s = t, i.e.. fourth letter is incremented by 1 position
s = r, i.e.. fifth letter is decremented by 1 position
z = a, i.e.. sixth letter is incremented by 1 position
m = l, i.e.. seventh letter is decremented by 1 position
We need to follow the same pattern for the given word ‘rtjbl’
r = decrementing 1 position = q
t = incrementing 1 position = u
j = decrementing 1 position = i
b = incrementing 1 position = c
l = decrementing 1 position = k
So, ‘rtjbl’ will be changed for ‘quick’ .
