Answer: the ratio of the costs of two houses is 4: 3 and the cost of the second house is ₹ 4,20,000 the cost of the first house is 5,60,000. If the cost of the first house was ₹ 70,000 more, the ratio of their costs is 3 : 2
Step-by-step explanation:
The ratio of the costs of two houses is 4 : 3
The cost of the second house = ₹ 4,20,000
The ratio means that 4 times of a certain amount is the cost of first house and 3 times of the same is the cost of first house.
Let 'x' be the certain amount , then
3x = 4,20,000
∴ x = 1,40,000
Then cost of the second house 4x = ₹ 5,60,000
If the cost of the first house was ₹ 70,000 more,
then the new cost = ₹ 5,60,000 + ₹ 70,000 = ₹ 6,30,000
Then new ratio of costs = 6,30,000 : 4,20,000
= 63 : 42
As both are multiples of 21, then the new ratio is 3: 2
