Answer 1

Answer:

70% of 300 is

$\frac{70}{100} \times 300 = 210$

Selling Price of 210 Sari

$sp = 1500 \times 210 \\ = 315000$

Selling Price of 90 sari

$sp = 1350 \times 90 \\ = 121500$

Total Selling Price,

$315000 + 121500 = 436500$

His Profit is 42000.

Then, Cost Price,

$cp = sp - profit \\ = 436500 - 436500 \\ = 394500$

Cost Price = 394500
