7 6 12
5 5 7
4 6 ?
168 90 168​

Answer 1

Question :-

7 6. 12

5 5 7

4 6 ?

168 90. 168

Solution :-

The Above Problem is a Question From Matrix Chapter of Reasoning ... We Have to Find The Same Logic in All Three lines and Find Our answer .

Lets Try to Se Our Pattern :-

→ 7 - 5 - 4 = 168

Logic :- [ First Number * (Second Number + 1) * Third Number ] ÷ 1 = 168 .

Check :-

→ [ 7 * (5 + 1) * 4 ] ÷ 1

→ [ 7 * 6 * 4 ] ÷ 1

→ 168 ÷ 1

→ 168 = Satisfy.

____________________________

Next Logic :- [ First Number * (Second Number + 0) * Third Number ] ÷ 2 = 90

Check :-

→ [ 6 * (5+0) * 6 ] ÷ 2

→ [ 6 * 5 * 6 ] ÷ 2

→ [ 180 ] ÷ 2

→ 90 = satisfy.

_____________________

So, Next Logic :- [ First Number * (Second Number - 1) * Third Number ] ÷ 3 = 168

Check :-

→ [ 12 * ( 7 - 1) * x ] ÷ 3 = 168

→ [ 12 * 6 * x ] ÷ 3 = 168

→ (72* x)/3 = 168

→ 72x = 168 * 3

→ 72x = 504

→ x = 7. (Ans).

Hence, Right Answer will be 7.

Answer 2

Step-by-step explanation:

THERE IS ALWAYS A PATTERN IN SUCH QUESTIONS LIKE IN THIS TOO :-

[ 1st No. × (2nd No. + 1 ) × 3rd No. ] ÷ 1

1) 7 5 4 = 168

= [ 7 × ( 5 + 1 ) × 4 ] ÷ 1

= [ 7 × 6 × 4 ] ÷ 1

= 168 ÷ 1

= 168

NOW,

[ 1st No. × ( 2nd No. + 0 ) × 3rd No. ] ÷ 2

2) 6 5 6 = 90

= [ 6 × ( 5 + 0 ) × 6 ] ÷ 2

= [ 6 × 5 × 6 ] ÷ 2

= [ 180 ] ÷ 2

= 90

NOW,

[ 1st No. * ( 2nd No. - 1) * 3rd No. ] ÷ 3

3) 12 7 ? = 168

= [ 12 × ( 7 - 1 ) × x ] ÷ 3 = 168

= [ 12 × 6 × x ] ÷ 3 = 168

= (72 × x ) / 3 = 168

= 72x = 168 × 3

= 72x = 504

= x = 7
