Let us assume the present ages of woman and her daughter be 2x and x years respectively ; then
According to question,
The average age of a woman and her daughter is 42 years
(2x + x)/2 = 42
? 3x = 84
? x = 28
Hence, present age of her daughter = 28 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
