Answer 1

Answer:

750

Step-by-step explanation:

20x8=160

Cost is 400 for 160 pencils

For 1 pencil is 400/160 = 2.5

So for 25x12= 300 pencils

Total cost is 300x2.5= 750

Answer 2

₹750

Step-by-step explanation:

since,20 packets of 8 pencils cof cost 400

so, 160 (20×8) pencils = ₹400

now ,we have to find the cost of 25 packets of 12 pencils

cost of one pencil = 400/160

number of pencils in 25 packets of 12 pencils = 25 × 12 = 300

since,160 pencils cost ₹400

so , 300 pencils will cost = 400/160 ×300

= ₹750
