Question

What is solution of this question

Answer 1

The answer to this question should be 50 i.e Option d)

Explanation:

If we look at the problem carefully,the following sequence can be identified:-

1st Triangle: $5+3+4+1+8 = 21$

2nd Triangle: $3+3+5+6+5 = 22$

3rd Triangle: $9+6+3+a+b = 23$

From the above sequence,it can be construed that the sum of all digits of each triangle comes out to be 21,22 and 23.

Now,we need that last 2 digits which are summing up to 23 in the 3rd Triangle.

The last 2 digits can only be 5 and 0 as any other digit in the given options will not form 23 on considering.

Therefore,the 4th option(option d) i.e 50 is correct.
