Question

if difference of squares of b and a is 2013, find ab

Answer 1

ending number of square numbers comes = 0,1,4,5,6,9

for difference comes 3, ending number of squares should be either it is 1&4 or 6&9

√2013 come 44.86...

So let us take 47² = 2209

2209 - 2013 = 196 ie. 14²

So numbers are 47 and 14

so ab = 47 x 14 = 658
