Let the present ages of Suresh and his daughter be 2x and x years respectively; then
According to question,
Six years hence, the ratio of their ages would be 23 : 13
(2x + 6) / (x + 6) = 23/13
? (2x + 6) 13 = 23 (x + 6)
? 26x + 78 = 23x + 138
? 3x = 60
? x = 20
Hence, present age of Suresh = 2 x 10 = 40 years
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
