Question

Mother's weight is $25\%$ more than that of daughter. What percent is daughter's weight less than mother's weight?

• A. $20$%
• B. $30$%
• C. $25$%
• D. $35$%

Answer 1

The correct option is A $20$%

Let daughter's weight be $100kg$.

Then mother's weight $=(100+25)kg=125kg$

If mother's weight is $125kg$, then daughter's weight is $100kg$.

If mother's weight is $1kg$, then daughter's weight is $\frac{100}{125}kg$

If mother's weight is $100kg$, then daughter's weight $=(\frac{100}{125}\times 100)kg$

$\therefore$, daughter's weight is $20\%$ less than that of mother.
