There are positive integers that have these properties: the sum of the squares of their digits is 50, and each digit is larger than the one to its left. The product of the digits of the largest integer with both properties is
a)36
b)25
c)7
d)48

• answer is 36
  let us first see the no. with square less than 50
  1*1=1,2*2=4,3*3=9,4*4=16,5*5=25,6*6=36,7*7=49
  so now we need to get sum of squares to be 50 and also to choose the largest integer so
  let's try 17,1+49=50 but its surely not the largest
  now try 345,9+16+25 but still there is largest integer
  now try 1236,1+4+9+36 and you got the answer
  now product of digits 1*2*3*6=36.

• ans:36 the digits are 1,2,3,6 so addition of these squares is 50 and right is always greater than left

• The correct answer will be 25
  
  because 5^2 + 5^2 = 50
  
  and also 5*5 = 25 (in this 2 is in left side which is small and 5 is in right side which is larger than left side)
