यदि 5×9=144, 7×8=151, 4×6=102, 2×5=?

Answer 1

hi

there is a pttern behind this question

 5×9=144, 7×8=151, 4×6=102, 2×5=?

so how  5×9=144??

9 + 5 =14

9 - 5= 4

so  5×9=144

in the same way as follows,

7 *8 = 151

7+8 = 15

8 - 7= 1

-------------------

4 *6 = 102

6+4 = 10

6 - 4 = 2

--------------

so now

2 * 5 = ?

= 2+5 = 7

5 - 2= 3

hence 2×5=73

hope it helps u
