Given:

एक लाल फिता का 1/4 हिस्सा तुमने लिया और आपके भाई ने तुम्हारे हिस्से में से 2/7 हिस्सा लिया तो फिता का कितना हिस्सा बचा रह गया

Solution:

Know that the complete part of the ribbon is x,

Since I take \[\frac{1}{4}\] parts of the ribbon,

Therefore remaining part is \[ = x\frac{3}{4}\].

Now my brother takes \[\frac{2}{7}\] from my part,

Calculate the remaining part of the ribbon to me,

\[ = \frac{x}{4} - \frac{x}{4} \times \frac{2}{7}\]

\[ = \frac{x}{4} - \frac{x}{{14}}\]

\[ = x\left( {\frac{{7 - 2}}{{28}}} \right)\]

\[ = x\frac{5}{{28}}\]

Now calculate the overall remaining ribbon,

\[ = \frac{{5x}}{{28}} + \frac{{3x}}{4}\]

\[ = \frac{{5x + 21x}}{{28}}\]

\[ = \frac{{26x}}{{28}}\]

\[ = \frac{{13}}{{14}}x\]

Hence the correct answer is option (d) i.e. \[\frac{{13}}{{14}}\]
