Question

10 boxes with 30 pencil cost rupees 600 watt would be the cost of 20 boxes with 18 pencil each​

Answer 1

Answer:

720

Step-by-step explanation:

10 boxes with 30 pencil = 600 rupees

Thus, 10 boxes contain total of 300 pencil = 10x30

= 300 pencils

Using unitary method the cost of 1 pencil = 600/300

= 2 rupees

Therefore, the cost of 20 boxes with 18 pencils = 720 rupees

= 2( 20x18)

= 2(360)

= 720

Hence the cost of 20 boxes with 18 pencils = 720

Cost of each pencil is 2 rupees
