Question

Price of 250gm of mangoes is Rs. 7.50. What is the price of 5kg of mangoes?

Answer 1

Step-by-step explanation:

first we will find the value of 1 kg

so, 1000-250 = 750

now 750 is the 3 rd part if we divide 1000 by 4

multiply 3× 7.50

= ₹ 22.50

5 kg = 5×22.50=112.50

the cost of 5 kg mangoes is ₹ 22.50
