Let us assume the present age of son be x then present of Deepak be 3x.
Five years hence, the ratio of their ages will be 34 : 13 respectively.
then according to question,
(3x + 5)/(x + 5) = 34/13
? (3x + 5) 13 = 34 (x + 5)
? 39x + 65 = 34x + 170
? 5x = 105
? x = 21
Hence, present age of Deepak = 3x = 3 x 21 = 63
In all the numbers except 383, the middle digit is the product of the other two digits.
All are multiple of 3 except 83.
Similarly, 32:112:(2/7)
32 ? 3 x 2 = 6
'Uneasy' and 'Quiet' are opposite to each other. Likewise, 'Fit' and 'Unfit' are opposite to each other
