Question

Find the missing number?
51 11 61
64 30 32
35 ? 43​

Answer 1

Given:- 51 11 61

64 30 32

35 ? 43

To find:- Find the value of missing number.

Solution:-

51 (11) 61

(5*1) + (6*1) = 5+6 = 11

We observed that in each row, the second number =( product of the digits in the first number + product of the digit in the third number)

64 (30) 32

(6*4) + (3*2) = 24 + 6 = 30

Like previous two , last step also follow the same rule.

in each row, the second number =( product of the digits in the first number + product of the digit in the third number)

35 ? 43

The missing number = (3*5) + (4*3) = 15 + 12= 27

The missing number is 27.

51 11 61

64 30 32

32 35 27 43

The option B is correct.(ans)

Answer 2

We have:

51   11  61

64  30 32

35   ?  43​

We have to find, the value of missing number.

Solution:

The pattern follow row-wise:

Second term = Product of first term + Product of third term

In first row,

11 = 5 × 1 + 6 × 1 = 5 + 6 = 11

In second row,

30 = 6 × 4 + 3 × 2 = 24 + 6 = 30

In third row,

? = 3 × 5 + 4 × 3

⇒ ? = 15 + 12

⇒ ? = 27

Thus, the required "option B) 27" is correct.
