Pattern is: multiply the first number by 5 and then reverse the number thus obtained to get the second number.
9 × 5 = 45, 9 + 54 = 63

7 × 5 = 35, 7 + 53 = 60

3 × 5 = 15, 3 + 51 = 54

But,

8 × 5 = 40, 8 + 04 = 12 not 44, therefore, (8 : 44) is the odd one out.

Hence, option D is the correct answer.

Here we can conclude two cases from the given statements.

Case 1: Case 2:

In case 1:

Conclusion I: Some laptops are black – False.

Conclusion II: No black is a laptop – True, it is a negative and definite case.

In case 2:

Conclusion I: Some laptops are black – True, it is a definite case.

Conclusion II: No black is a laptop – False.

So, either conclusion I or II follows.

Hence, option C is the correct answer.

Amount with interest after 4 years = Rs. 36000

Let P be the principle amount.
Then,
Simple Interest = 36000 − P

P = Rs. 30000

Alternate approach:

Effective interest for four years = 4×5% = 20%
Therefore,
According to the question
120% of Principal = Rs.36000

100% of Principal = (36000/120)×100 = Rs.30000

As shown above in the figure,

Surface area of the cuboid = 2(5 × 4 + 4 × 3 + 5 × 3)

= 2(20 + 12 + 15) = 2 × 47 = 94 m²

Area of the circular opening = Π(1)²

= 3.14 × 1 = 3.14 m²

 Metal required will be

= 94 − 3.14 = 90.86 m²

Hence, option (B) is the correct answer.
