Divide ₹ 4,500 into two parts in the ratio 2 : 3. Class 8

Divide ₹ 4,500 into two parts in the ratio 2 : 3. Class 8

Question 1.

Divide ₹ 4,500 into two parts in the ratio 2 : 3. Class 8

Solution:

First part = ₹ [latex]\frac{4500}{(2+3)}[/latex] × 2 = ₹ 1800

Second part = ₹ [latex]\frac{4500}{(2+3)}[/latex] × 3 = ₹ 2700

Question 2.

In a science lab, acid and water are mixed in the ratio of 1 : 5 to make a solution. In a bottle that has 240 mL of the solution, how much acid and water does the solution contain? Class 8

Solution:

Acid = [latex]\frac{(240)}{1+5}[/latex] × 1 = [latex]\frac{240}{6}[/latex] × 1 = 40 mL

Water = [latex]\frac{240 \times 5}{1+5}=\frac{240}{6}[/latex] × 5 = 200 mL
