Answer 2

Step-by-step explanation:

given :

1. reduction of 20% in the price of wheat

• 4 kilo more for ₹ 120

2. triangle whose base is 25 cm and altitude 14 cm

cost of painting be ₹4.80 per sq cm

to find :

1. What is the reduction price per kilo? What was the price per kilo before reduction = ?

2. Find the cost of painting a piece of cloth = ?

solution :

ans 1

kilograms 4 = ₹ 120

kilograms 1 = 120/4

kilograms = ₹30

• price of wheat reducing = 20%

price of wheat reducing = 20/100 × 30

• price of wheat reducing = ₹6

wheat of price reducing = ₹6

per kilo before reduction = ₹30

ans 2 :

given base = 25

altitude = 14 cm

• formula of area traingular = 1/2 × b × h

traingular area = 1/2 x 25× 14

traingular area = 12.5

• cost of painting = ₹4.80 per sq m

• then we will multiply 175 with 4.80

175 × ₹4.80 = rs 840

hence, the cost of painting = rs 840
