A) Only Statement-1
B) Only Statement-2
C) Both Statement-1 and Statement-2
D) Neither Statement-1 and nor Statement-2
Correct Answer: B
Solution :
Statement-1: Total quantity of milk bought \[=7\frac{1}{2}\] litres \[=\frac{15}{2}\]litres Quantity of milk consumed \[=5\frac{3}{4}\text{litres}\] \[=\frac{23}{4}\text{litres}\] \[\therefore \] Quantity of milk left \[=\left( \frac{15}{2}-\frac{23}{4} \right)\]litres \[=\left( \frac{30-23}{4} \right)\text{litres=}\frac{7}{4}\] litres \[=1\frac{3}{4}\text{litres}\] Statement ? 2: Let total number of pages in the book be x. According to question, \[\frac{3}{5}x+80=x\] \[\Rightarrow x-\frac{3}{5}x=80\Rightarrow \frac{2x}{5}=80\Rightarrow x=\frac{80\times 5}{2}\] \[\Rightarrow x=200\] \[\therefore \] Total number of pages =200 Hence, only statement-2 is true.You need to login to perform this action.
