Explanation

We are given:

• 35 kg of spinach costs Rs. 28

• We need to find how many kg can be bought for Rs. 16

Step 1: Find cost per kg

Cost per kg==28​/35=0.8Rs/kg

Step 2: Find how many kg for Rs. 16

$$text{Kg} = frac{16}{0.8} = 20$$0.8=20

Explanation

Profit = Selling Price - Cost Price

= 390 - 300 = 90
Profit % = (Profit / Cost Price) × 100

= (90 / 300) × 100 = 30%

Explanation

 Selling Price = Cost + Profit

= 1500 + (15% of 1500) = 1500 + 225 = 1725

Explanation

 Let original price = x

Selling price = x + 15% of x = 1.15x = 1500

x = 1500 / 1.15 = 1275

Explanation

A man sold two scooters for 24000 each.

Find the cost price of one scooter at gain of 20% :-

C.P = (S.P × 100)/(100 + gain)

= (24000 × 100)/(100 + 20)

= 2400000/120

= 20000

Explanation

$$\text{Loss}=\text{Cost Price}-\text{Selling Price}$$ $$= 8000 - 7000 = 1000$$

Explanation

C.P = 2 Profit = 10%

S.P=?

S.P = C.P (100 +P%)/ 100 

S.P = 2 (100 + 10)/100

S.P = 27 (110) /100 

S.P = 29.7
