Unitary method pls​

Answer 1

1. Cost of 6 notebooks = ₹192

Cost of 1 notebook = 192/6

= ₹32

Cost of 30 notebooks = 32×30

= ₹960

2. In 64 seconds the boy runs = 72m

In 1 second the boy run = 72/64

= 1.125m

In 4.8 seconds the boy runs = 1.125×4.8

= 5.4m

3. Workers paid in 6 days = ₹1890

Workers paid in 1 day = 1890/6

= ₹315

Workers paid in 25days = 315×25

= ₹7875
