Q.3 If it has rained 276 mm in the last 3 days, how many cm of rain will fall in one full week (7 days)? Assume that the rain continues to fall at the same rate.
Answer :

In last 3 days the rain falls = 276 mm .
In 1 day the rain falls = 276/3mm.
in 7 days the rain will fall = 92 x 7 mm.
= 92 x 7 mm = 644 mm = 64.4 cm
Thus, the amount of rain fall in week = 64.4 cm.
