  • Selling Price (SP) = MP - Discount = 13019.5=110.5130 - 19.5 = 110.5.
  • Profit = SP - CP = 110.5100=10.5110.5 - 100 = 10.5.
  • Profit Percentage = 10.5%.

Question 48

#1298

In what time, does a sum of money become fourfold at the simple interest rate of 10% per annum?

A

40 years

B

30 years

C

15 years

D

None of the above

Correct answer keyB

Explanation

  • Let the principal be PP.
  • Amount = 4P4P, so Simple Interest (SI) = 4PP=3P4P - P = 3P.
  • Rate (R) = 10%10\% per annum.
  • Using formula: T=SI×100P×RT = \frac{SI \times 100}{P \times R}
  • T=3P×100P×10=30T = \frac{3P \times 100}{P \times 10} = 30 years.
  • The required time is 30 years.

Question 49

#1299

What will be the answer of this BODMAS question? 1724÷6×4+817-24 ÷ 6 × 4 + 8

A

8

B

9

C

24

D

60

Correct answer keyB

Explanation

  • Apply BODMAS: 1724÷6×4+817 - 24 \div 6 \times 4 + 8
  • Division first: 24÷6=424 \div 6 = 4
  • Expression becomes: 174×4+817 - 4 \times 4 + 8
  • Multiplication: 4×4=164 \times 4 = 16
  • Expression becomes: 1716+817 - 16 + 8
  • Addition/Subtraction (left to right): 1716=117 - 16 = 1
  • 1+8=91 + 8 = 9
  • The answer is 9.

Question 50

#1300

12 men can do a piece of work in 24 days. How many days are needed to complete the work, if 8 men are engaged in the same work?

A

28

B

36

C

48

D

50

Correct answer keyB

Explanation

  • Using the formula M1×D1=M2×D2M_1 \times D_1 = M_2 \times D_2
  • Here, M1=12M_1 = 12, D1=24D_1 = 24, M2=8M_2 = 8, and we need to find D2D_2.
  • 12×24=8×D212 \times 24 = 8 \times D_2
  • 288=8×D2288 = 8 \times D_2
  • D2=2888=36D_2 = \frac{288}{8} = 36
  • It will take 36 days.
