Answer 1

560000 is cost of house

Step-by-step explanation:

In this year's Madhymik examination out of 150 examinees of our school, 100

examinees passed with grade - A. In another nearby school out of 100 examinees, 80 examinees passed with grade

100/150  = 2/3  our school

80/100  = 4/5 other School

2/3 = 10/15

4/5 = 12/15

12 > 15

other school performed better

The ratio of the costs of two houses is 4 : 3 and the cost of the second house is 4,20,000

4 /3 = C/420000

=>C = 560000

560000 + 70000 = 630000

630000/420000  = 63/42  = 3/2

3 :2 is the Ratio
