Answer 1

Given - 2+3 = 8,

3+4= 15,

4+1= 4,

2+5= 14

Find - the answer for 10+9 =?

Answer - the given question is a logical reasoning question, which can only be solved in a particular pattern. The pattern to solve this question is as follows-

For 2+3=8

2*3+2

6+2

8

For 3+4 = 15

3*4+3

12+3

15

For 4+1 = 4

4*1+0

4

For 2+5 = 14

2*5+4

10+4

14

Hence, for 10+9 = ?

10*9+5

90+5

95

The numbers given are multiplied and then the product is added with numbers in following sequence - 2,3,0,4 and 5.

Hence, the logical answer for 10+9 = 95.

Answer 2

Answer:

98

Explanation:

Multiply the first number with the second and add the second number minus 1, uniformly for all equations.

(2*3)+3-1=8

(3*4)+4-1=15

(4*1) + 1 -1=4

(2*5)+5-1 =14

(10*9)+9-1=98
