Question

Divide 50 books between Sheela and Lata in the ratio 3 : 7.

Divide Rs 625 between Alok and Mohit in the ratio 2 : 3.

The ratio of the number of stamps collected by Susan and Latika is 5 : 7. If the total number of stamps that he has is 180, find the number of stamps in their individual collection.

Answer 1

No. of books sheela has $=\frac{3}{(7+3)}\times 50\Rightarrow \frac{3}{10}\times 50$

$=3\times 5=15$

No. of books Lata has $=\frac{7}{7+3}\times 50$

$=\frac{7}{10}\times 50=7\times 5=35$

Rs. Alok has $=\frac{2}{2+3}\times 625$

$=\frac{2}{5}\times 625=Rs.250$

Rs. Mohit has $=\frac{3}{2+3}\times 625$

$=\frac{3}{5}\times 625=Rs.375$

No. of stamps with susan $=\frac{5}{5+7}\times 180\Rightarrow$ $\frac{5}{12}\times 180=5\times 15=75$

No. of stamps with Latika $=\frac{7}{5+7}\times 180\Rightarrow$ $\frac{7}{12}\times 180=7\times 15=105$
