If
19x17 = 62
23x14 = 61
then
13x15 =


a.60
b.25
c.98
d.33
e.51
f.84
g.42
h.35
i.55
j.none of these

• for
  19x17
  1*1 1*7 9*1 9*7=17963=1+7+9+6+3=26
  reversing gives 62
  
  23*14
  2*1 2*4 3*1 3*4=28312=16
  reverse gives 61
  
  so for
  13x15
  1*1 1*5 3*1 3*5=15315=1+5+3+1+5=15
  reversing gives 51
  ans is option e
