Explanation

To find the sale price, calculate 20% of the listed price (Rs. 160) and subtract that amount from the listed price.

20% of Rs. 160 = (20/100) x Rs. 160 = Rs. 32

Now, subtract Rs. 32 from Rs. 160:

Rs. 160 - Rs. 32 = Rs. 128

So, the correct answer is:

Rs. 128

Explanation

This is an alternating number subtraction series.

First, 2 is subtracted, then 4, then 2, and so on.

Explanation

The hands of a clock coincide 22 times in a 24-hour day.

• The hour and minute hands coincide once every 65 minutes (60 minutes + 5 minutes).
• Since there are 24 hours in a day, the hands coincide 24 x (24/65) = 22 times in a 24-hour day.

Explanation

To find the solution, first, calculate the total man-days required for the job: 36 men * 18 days = 648 man-days.

Then, divide the total man-days by the new number of men (27) to find the new number of days: 648 man-days / 27 men = 24 days.

So, the correct answer is 24.

Explanation

3+1 = 4

4+3 = 7

7+1 = 8

8+3 = 11

11+1 = 12

12+3 = 15
