Question

Q. A huge urn with a capacity of 100 litres, contains 35 litres of black tea (without milk). If a person filled the remainder of the urn with tea containing 40% milk b/v, what would be the overall milk content (b/v) in the urn now?

Q. 100 लीटर की क्षमता वाले एक विशाल पात्र में 35 लीटर काली चाय (दूध के बिना) है। यदि एक व्यक्ति ने पात्र के शेष भाग को 40% दूध (b/v) वाली चाय से भर दिया, तो अब पात्र में दूध की कुल मात्रा (b/v) क्या होगी?

Solution

The correct option is A 26%

The capacity of the urn =100 l

Remaining capacity after filling it with black tea =10035=65 l

So, the quantity of milk tea in the urn =65 l

% of milk in tea =40%

Quantity of milk =40100×65=26 l26%


पात्र की क्षमता =100 लीटर

काली चाय से भरने के बाद शेष क्षमता =10035=65 लीटर

अत: पात्र में दूध वाली चाय की मात्रा =65 लीटर

चाय में दूध का %=40%

दूध की मात्रा =40100×65=26L26%
