of cloth. Find the amount she has to pay for it and the total length of the cloth
purchased by her?​

Answer 1

Answer:

645.04 rupees

Step-by-step explanation:

1st piece costs 330/metre.

no.of metres purchased is 1.2cm (1.2/100 meters) , i.e, 0.012metres.

therefore the cost is 330*0.012=3.96 rs

2nd piece costs 270/metre.

no.of metres purchased is 1.3 metres

therefore the cost is 270*1.3=351 rs

therefore total cost of two pieces is 351rs+3.96rs=354.96rs

money paid in the counter is 1000rs

therefore the money to be returned is 1000rs-354.96rs=645.04rs
