The Correct Option is B
Solution and Explanation
We can solve this problem using only statement B.
Using Statement B
7 women complete the work in 14 days.
Let's find the work done by one woman in one day
Work done by 7 women in 1 day = \(\frac{1}{14}\)
Work done by 1 woman in 1 day = \(\frac{\frac{1}{14}}{7} = \frac{1}{98}\)
Now let's find how many women are needed to complete the work in 10 days
- Work done by 1 woman in 10 days = \(\frac{1}{98} \times 10 = \frac{10}{98} = \frac{1}{9.8}\)
- Number of women required to complete the work in 10 days = 9.8.
- Since we can't have fractions of people, we round 9.8 up to the nearest whole number.
Therefore, 10 women are needed to complete the work in 10 days
Final Answer: The statement B alone is sufficient to answer the question, but the statement A alone is not sufficient.
So the correct option is (B)

Mr. Kunal Dwivedi wants to buy a motorbike which is priced at Rs. 45,000. The bike is also available at Rs. 25,000 down payment and monthly installments of Rs. 1000 per month for 2 years or Rs. 18,000 down payment and monthly instalment of Rs. 1000 per month for 3 years. Mr. Kunal has with him only Rs. 12,000. He wants to borrow the balance money of the down payment from a private money lender whose terms are :
If Rs. 6,000 is borrowed for 12 months, the rate of interest is 20%. The interest will be calculated on the whole amount for the whole year, even though the repayment has to be done in 12 equal monthly instalments starting from the first month itself. Thus he will have to repay an amount of Rs. 600 per month for 12 months to repay Rs. 6000 (Principal) + Rs. 1,200 (Interest @ 20%).
If Rs. 10,000 upwards is borrowed for one year, the rate of interest is 30% and is calculated in exactly the same manner as above. - Refer to the following charts given in Fig 1, 2 & 3 to answer these questions.
