Question

If 5+3+5=151012 , 9+2+4=183652, 8+ 6+3 - 489466 the H2+5= a) 143543 b) 143547 c) 1435 49 d) NOTA​

Answer 1

There are a few patterns in this.

The first two digits of the sum are the product of the first and second numbers. For example,

5+3+2=15(5*3)1012

9+2+4=18(9*2)3662

The second pair of digits or the third and fourth digits of the sum are the product of the first and third numbers. For example,

8+6+3=4824(8*3)66

5+4+5=2025(5*5)04

The last pair of digits of the sum are the reverse of the product of the sum of the first and third number with the middle number. For example,

5+3+2=(5+2)*3=21.

Reverse=12

Sum=151012

5+4+5=(5+5)*4=40

Reverse=04

Sum=202504

Going by the same patterns,

7+2+5= 143542
