The correct answer is option 3 i.e. PM27.

Given series: HW19, JU21, LS23, NQ25, PM27

H + 2 = J, J + 2 = L, L + 2 = N, N + 2 = P

W - 2 = U, U - 2 = S, S - 2 = Q, Q - 2 = O ≠ M 

19 + 2 = 21, 21 + 2 = 23, 23 + 2 = 25, 25 + 2 = 27 

Hence, the correct answer is PM27.

The correct answer is option 2 i.e. ÷, ×, +, -.

Option 2) ÷, ×, +, -

= (55 ÷ 5) × 4 + 14 - 20

= (11 × 4) + 14 - 20

= (44 + 14) - 20

= 58 - 20

= 38 = RHS

Hence, the correct answer is ÷, ×, +, -.

The correct answer is Option 2 i.e. ÷, +, ×, -.

Option 2: ÷, +, ×, -

= 16 ÷ 4 + 17 × 2 - 10

= 4  + 17 × 2 - 10

= 4 + 34 - 10

= 38 - 10

 = 28

Hence, the correct answer is ÷, +, ×, -.

The correct answer is option 1 i.e.Tuesday.

12th March 2024 is Sunday.

After 12th March to 11th July ⇒ 19 + 30 + 31 + 30 + 11 = 121 days

Therefore, 121 ÷ 7 = 2 is the remainder

So, Sunday + 2 days = Tuesday

Hence, the correct answer is Tuesday.

The correct answer is Option 4 i.e. Rs. 98000.

S.I. = (P × R × T)/100

here, S.I. = Simple Interest, P = Principal, R = Rate, and T = Time

⇒ S.I. = (50000 × 12 × 8)/100

⇒ S.I. = 500 × 12 × 8

⇒ S.I. = Rs. 48000

Amount = Interest + Principal

Amount = 48000 + 50000

Amount = Rs.98000

The correct answer is option 4 i.e. 300 metres.

Let the radius of outer circle and inner circle be R and r respectively.

According to the question

Outer circumference/Inner circumference =  2πR/ 2πr = R/r = 17/15

The width of path = R - r = 17 - 15 = 2 units

⇒ 2 units =  40 m

⇒ 1 unit = 20 m

⇒ 15 units = 15 × 20 = 300 m

Hence, the inner radius r is 300 meters

The correct answer is option 4 i.e. 289 g.

According to the question

⇒ 0.15 = 51 g 

⇒ 1 = 51/0.15 = 340 g

Now, 0.85 = 0.85 × 340 = 289 g

Hence, the other element of the alloy = 289 g

The correct answer is option 1 i.e. ₹20,000

Marked Price × (100 − 15)/100 × (100 − 25)/100 = 12750

Marked Price × 17/20 × 3/4 = 12750

Marked price = 20000

The correct answer is Option 2 i.e. 3 : 1.

Let the work capacity of one man be x and the work capacity of one boy be y

⇒ 6x + 2y = 5(x + y)

⇒ 6x + 2y = 5x + 5y

⇒ x = 3y

⇒ x/y = 3/1

⇒ x : y = 3 : 1

The ratio of the working capacity of a man to that of a boy is 3 : 1

The correct answer is option 3 i.e. Rs 50000.

Let the cost price for the manufacturer be Rs 100x.

Selling price for the manufacturer will be 110x

The selling price for a wholesale dealer will be: 110x × 1.2

⇒ 132x

After giving a 15% discount: 

⇒ 132x × 0.85 = 112.2x

⇒ 112.2x = 56100

⇒ x = 500

⇒ Cost price for manufacturer = 100x

⇒ 100(500) = Rs 50,000
