Answer 2

$\bf \red{87 \times 34 = 2}$

Option (d) is correct.

Correct Question:

Given:

• If $32 \times 21 = 62$
• $94 \times 67 = 88$

To find:

• Find the value of $87 \times 34$
• a) 16
• b) 22
• c) 8
• d) 2

Solution:

Step 1:

Analysing the pattern.

As,

$32 \times 21 = 62$

that means

$3 \times 2 = 6 \\ 2 \times 1 = 2$

So,

$32 \times 21 = 62$

i.e. The digits of numbers are multiplied.

In the second,

$94 \times 67 = 88$

Let us check that the pattern follows or not

$9 \times 4 = 36 \\ 3 \times 6 = 18 \\ 1 \times 8 = 8$

and

$6 \times 7 = 42 \\ 4 \times 2 = 8$

Thus,

$94 \times 67 = 88$

Step 2:

Now find the value of $87 \times 34$

Multiplies the digits of numbers,

$8 \times 7 = 56 \\ 5 \times 6 = 30 \\ 3 \times 0 = 0$

and

$3 \times 4 = 12 \\ 1 \times 2 = 2$

So,

$87 \times 34 = 02$

Thus,

$\bf 87 \times 34 = 2$

Option d is correct.
