उत्तर
Water flows through a river in each day = 230000000000 or 230 billion
Water flows through the river in a week = 7 × 230000000000 ...[∵ 1 week = 7 days]
= 1610000000000
= 1610 billion
= 1.61 × 1012 L
Water flows through the river in a year = 230000000000 × 365 ...[∵ 1 yr = 365 days]
= 83950000000000
= 8.395 × 1013 L
