Question

A city had 32.22 mm of rain on Sunday. On Monday, it increased by 3.23 mm and on Tuesday, it decreased by 5.55 mm. A similar pattern was predicted to be
followed on subsequent days. How much rainfall will occur on Saturday?​

Answer 1

Step 1:

Sunday = 32.22 mm of rain

Step 2:

Monday = it increased by 3.23 mm = 32.22 + 3.23 = 35.45

Step 3:

Tuesday = it decreased by 5.55 mm = 35.45 - 5.55 = 29.90

Step 4:

Wednesday = it increased by 3.23 mm = 29.90 + 3.23 = 33.13

Step 5:

Thursday = it decreased by 5.55 mm = 33.13 - 5.55 = 27.58

Step 6:

Friday = it increased by 3.23 mm = 27.58 + 3.23 = 30.81

Step 7:

Saturday = it decreased by 5.55 mm = 30.81 - 5.55 = 25.26

Hence, 25.26 rainfall will occur on Saturday.
