If we divide a two digit number by the sum of its digits we get 4 as a quotient and 3 as a remainder. Now if we divide that two digit number by the product of its digits we get 3 as a quotient and 5 as a remainder . Find the two digit number? |
| A) 12 B) 17
C) 21
D) 23 Correct Answer : 23 Explanation :
Given that n(x, y) / (x+y) Given that n(x, y)/(x*y) quotient = 3 and remainder = 5 x=2 or 1/2 y=2a−1=2*2-1=3 n(x, y)=10x+y= 23 is required number |
