for Rs 350. If pencils costs Rs 190.50
and erasers cost Rs 30.50 then
find the cost of the notebooks.​

Answer 1

Answer:

Let cost of notebooks be x

total cost(t)=₹350

eraser cost(e)=₹30.50

pencil cost(p)=₹190.50

hence cost of notebooks X:

X=t-(p+e)

X=350-(190.50+30.50)

X=350-221

X=129.

ANS: Cost of notebooks is ₹129
