Answer 1

the correct answer of this question is D)45

Answer 2

Answer:

The value of 54*32 is 45.

Given:

given terms are

5*71=40,

92*23=55,

37*44= 80,

to find:

then 54*32=?

Step-by-step explanation:

Given terms are

5*71=40,

92*23=55,

37*44= 80,

It is very evident from the given pattern the answer is obtained by multiplying the sum of digits of the number.

In 5*71=40,

5 x (7+1)    (Sum of digits is multiplied)

5 x 8 =40

In 92*23=55

( 9 +2 ) x ( 2+ 3 )      (Sum of digits is multiplied)

11 x 5 = 55

In 37*44= 80

( 3 + 7 ) x ( 4 + 4)      (Sum of digits is multiplied)

10 x 8 = 80

In 54*32

( 5 + 4 ) x ( 3 + 2)          (Sum of digits is multiplied)

9 x 5 = 45

Hence the value of 54*32 is 45 .
