Chicken eggs | 20 Paise each |
Century eggs | 90 Paise each |
Quail eggs | 5 Paise each |
A) Rs. 1.25
B) Rs. 1.40
C) Rs. 1.65
D) Rs. 1.80
Correct Answer: A
Solution :
Let the total number of eggs be X. \[\therefore \]Number of chicken eggs \[=\frac{1}{4}X\] Number of century eggs \[=\frac{1}{8}X\] And number of quail eggs \[=X-\left( \frac{1}{4}X+\frac{1}{8}X \right)=\frac{5}{8}X\] Now, \[\frac{1}{4}\times X\times 20+\frac{1}{8}\times X\times 90=6.50\times 100\]paise \[\Rightarrow \] \[\frac{40X+90X}{8}=650\] \[\Rightarrow \]\[130X=\text{ }5200\]\[\Rightarrow \] \[X=40\] \[\therefore \]Number of quail eggs \[=\frac{5}{8}\times 40=25\] So, money spent on quail eggs \[=\text{ }\left( 25\times 5 \right)\]paise \[=\text{ }125\]paise = Rs. 1.25.You need to login to perform this action.
