Having good practice on logical reasoning math questions is very important to
crack any online written test. To solve logical reasoning math questions, you
do not need to know complex math formulas. You just need to have basic math
skills (Addition, Subtraction, Multiplication and Division) along with logical
thinking.
However, the most important thing over here is the time that you are taking to
solve the question. If you are able to solve the logical reasoning math
question within a minute then you will get enough time to solve other criteria
questions which may take more time. So that, you can easily crack any online
written test.

Logical Reasoning Math Question:
Find the number which replaces the question mark.
3+2 = 7
5+4 = 23
7+6 = 47
9+8 = 79
10+9 = ?
Answer Explanation For Logical Reasoning Math Question:
Take the first equation i.e., 3+2 = 7. Consider this as A+B = C. Then the
actual logic behind this is A*B+(B-1) = 3*2+(2-1) = 7. Lets implement this on
all the given equations.
3+2 = 7 (Actual Logic: 3*2+1= 7)
5+4 = 23 (Actual Logic: 5*4+3 = 23)
7+6 = 47 (Actual Logic: 7*6+5= 47)
9+8 = 79 (Actual Logic: 9*8+7 =79)
10+9 = ? (Actual Logic: 10*9+8 = 98)
So, the answer is 99.
Tip: Do not look only at the first
equation (i.e., 3+2 = 7) and start thinking how it is equal to 7. Look at two
or three equations and try to find the common thing in it. In this scenario,
the common thing is A*B+(B-1). You may not get it, but you will definitely get
it after practicing these kinds of questions regularly.

If 3+2 = 7 -----> 3*2+1=7
5+4 = 23 ------>5*4+3=23
7+6 = 47 ------> 7*6+5=47
9+8 = 79--------> 9*8+7=79
Then, 10+9 = ? ----------> 10*9+9=99

this answer can be 99 if the question will be 10+10
but here the trick in this question is for the 2nd element is now an odd number='9'
the method of adding incremented odd value can not be applicable.so,we have to follow the rule A*B+(B-1)=Ans

98
Exactly , the correct answer is "98"
Bcz from the beginning it follows a particular logic i.e A+B-(B-1) = 3*2-(1)=5 , So at the end also follows the same ,
10*9-(9-1) = 98.//
