A can do a work in 10 days, B can do the same work in 20 days. After working for 4 days B left the job & C started working at the place of B, the remaining work was done by both A & C in 2 days. In how many days C alone can do the work?

Solution

Work and Time – Find Days for C

A's 1 day work: 110
B's 1 day work: \frac{1}{20}

Step 1: A and B work for 4 days:
Work done = 4 \times \left( \frac{1}{10} + \frac{1}{20} \right) = 4 \times \frac{3}{20} = \frac{3}{5}

Remaining work: 1 - \frac{3}{5} = \frac{2}{5}

Step 2: A and C do remaining work in 2 days:
2 \times \left( \frac{1}{10} + \frac{1}{C} \right) = \frac{2}{5}

Dividing both sides by 2:
\frac{1}{10} + \frac{1}{C} = \frac{1}{5}

\frac{1}{C} = \frac{1}{5} - \frac{1}{10} = \frac{1}{10}
\Rightarrow C = 10

✅ Final Answer: 10 days

Solution

MCA NIMCET PYQ 2022
Running at the same constant rate, 6 identical machines can produce a total of 270 bottles per minute. At this rate, how many bottles could 10 such machines produce in 4 minutes?

Solution

Let the required number of bottles be x.

More machines, More bottles (Direct Proportion)

More minutes, More bottles (Direct Proportion)

\begin{matrix}{\begin{matrix}{Machines} & {6\colon10}\end{matrix}} \\ {\begin{matrix}{Time} & {\, \, \, \, \, \, \, \, \, \, 1\colon4}\end{matrix}}\end{matrix}\Bigr{\}}: : 270:x

∴6×1×x=10×4×270 

⇒x= \frac{(10×4×270)}{6}

​⇒x=1800
