20 men can earn ₹520 in 6 days. How much money will 18 men earn in 10 days?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ₹780
If 20 men can earn ₹520 in 6 days, we can find the earnings per man per day by dividing the total earnings by the number of men and the number of days:
Earnings per man per day = Rs. 520 / (20 men × 6 days)
Earnings per man per day = Rs. 520 / 120
Earnings per man per day = Rs. 4.33 (rounded to two decimal places)
Now, we can calculate the total earnings for 18 men in 10 days by multiplying the earnings per man per day by the number of men and the number of days:
Total earnings for 18 men in 10 days = Rs. 4.33 × (18 men × 10 days)
Total earnings for 18 men in 10 days = Rs. 4.33 × 180
Total earnings for 18 men in 10 days = Rs. 779.40 (rounded to two decimal places)
Therefore, 18 men will earn approximately Rs.780 in 10 days.
