Answer 2

Answer:

30 + 2 = 5

Step-by-step explanation:

Given :- The given expressions are: 60 + 7 = 4, 70 + 8 = 6, 80 + 9 = 8.

To Find :- The value of ? in 30 + 2 = ?

Solution :-

Here, 1st we need to look at the expressions and the value assigned to it and observe if there is any pattern. Then according to that pattern we will find the value of the expression 30 + 2 .

( a ) 60 + 7 = 4 :-  6 + 7 = 13

                            1 + 3 = 4

So, 60 + 7 = 4

( b ) 70 + 8 = 6 :-  7 + 8 = 15

                            1 + 5 = 6

So, 70 + 8 = 6

( c ) 80 + 9 = 8 :-  8 + 9 = 17

                             1 + 7 = 8

So, 80 + 9 = 8

( d ) 30 + 2 = ? :-  3 + 2 = 5

So, 30 + 2 = 5

Therefore, 30 + 2 = 5.
