Two sums of money are proportional to 8:9.n if the first is 20/- the other is
9/8 * 20 = 180/8 = 22.5
I do not understand why you inserted
.n" and "/-" into your question. The word "if" should be capitalized since it appears to start a sentence.
8/9=20/x
8x=20*9
8x=180 Divide with 8
x=180/8
x=(2*2*45)/(2*2*2)=45/2=22.5
To find the second sum of money, we can set up a proportion using the given ratio:
Let's represent the first sum of money as x and the second sum of money as y.
According to the given information, the ratio of the two sums of money is 8:9, which can be written as:
x/y = 8/9
Now, substitute the value of the first sum of money:
20/y = 8/9
To solve for y, cross-multiply:
8y = 20 * 9
8y = 180
Divide both sides of the equation by 8 to find y:
y = 180 / 8
y = 22.5
Therefore, the second sum of money is Rs. 22.50.
