The pattern is:
10 x 1.5 = 15
15 x 2.5 = 37.5
37.5 x 3.5 = 131.25
131.25 x 4.5 = 590.62
590.62 x 5.5 = 3248.41
Hence, option D is the correct answer.

The pattern is: place value of letters is taken as the number code.

L = 12

A = 1

M = 13

I = 9

N = 14

A = 1

T = 20

E = 5

Similarly, the code for SYSTEMIC is:

S = 19

Y = 25

S = 19

T = 20

E = 5

M = 13

I = 9

C = 3

Hence, option C is the correct answer.

Length of the longest scale = HCF (144, 180, 384)

HCF by prime factorization method:

144 = 2⁴ × 3²

180 = 2² × 3² × 5

384 = 2⁷ × 3

HCF (144, 180, 384) = 2² × 3 = 12 m

Length of the longest scale = 12 m

Hence, Option D is the right answer.

Let S.P. of T-shirt = LCM(9,18) = 18 unit

Now If Rahul sold T-shirt at  of its selling price, he suffers a loss of 20%.

Price at which Rahul sold T-shirt =  unit

C.P. of T-shirt = 100 %

Loss % when Rahul sold T-shirt at  of its selling price = 20%

S.P. when Rahul sold T-shirt at  of its selling price = 100 - 20 = 80%

So, 16 unit = 80%

1 unit = 5 %

S.P. when same T-shirt is sold at  of its selling price =  unit

21 unit = 21 × 5% = 105 %

So, Profit percentage = 105% -100% = 5%

Ratio of efficiency of 

Ratio of efficiency of

Total efficiency of A, B and C = 12 (on equalizing the ratios)

ATQ, Total work is completed in 30 Days; so the total work would be 30 × 12 = 360 units.

Efficiency of B = 12 – 7 = 5 unit/day

Time taken by B to complete the work = 360/5 = 72 days.
