Question : A, B and C were partners in a firm sharing profits in a 3: 3: 2 ratio. They admitted D as a new partner for 4/7 profit. D acquired his share 2/7 from A, 1 / 7 from B and 1 / 7 from C. The new profit sharing ratio will be
Option 1: 5:13:6:32
Option 2: 5:13:6:4
Option 3: 3: 3: 2: 4
Option 4: None of the above
Correct Answer: 5:13:6:32
Solution : Answer = 5:13:6:32 A's share $=\frac{3}{8}-\frac{2}{7}=\frac{21-16}{56}=\frac{5}{56}$ B's share $=\frac{3}{8}-\frac{1}{7}=\frac{21-8}{56}=\frac{13}{56}$ C's share $=\frac{2}{8}-\frac{1}{7}=\frac{14-8}{56}=\frac{6}{56}$ D s share $=\frac{4}{7}$ Thus, the new profit-sharing ratio for A, B, C and D will be : $\frac{5}{56}: \frac{13}{56}: \frac{6}{56}: \frac{4}{7} \text { or } \frac{5: 13: 6: 32}{56} \text { or
Question : Under which Article of the Directive Principles of State Policy, a working woman on maternity leave must receive all maternity benefits from the employer?

Article 42 emphasises the importance of ensuring fair and humane working conditions and providing maternity relief for working women. However, as mentioned earlier, it's a directive principle and not directly enforceable by the courts. Maternity benefits for working
Question : Directions: In a certain code language, RAUGHT is written as TYWEJR, and DOMINE is written as FMOGPC. How will BACKER be written in that language?
Option 1: DYEJIP
Option 2: DYEKGP
Option 3: DYEIHP
Option 4: DYEIGP
Correct Answer: DYEIGP
Solution : Given: RAUGHT is written as TYWEJR, and DOMINE is written as FMOGPC.
Add and subtract 2 alternatively from the place value of the letters of RAUGHT, and DOMINE to obtain the code – RAUGHT→R + 2 = T; A – 2 = Y; U +
Hello,
To be eligible for NEET 2024, you must fulfill the eligibility criteria set by the National Testing Agency (NTA). Generally, the minimum qualifying marks for NEET are 50% for General category and 40% for reserved categories. So, since you qualify the criteria, you are definitely eligible for NEET 2024.

Question : Rearrange the parts of the sentence in the correct order.
P. requires knowledge of the complex interplay among ocean Q. chemistry and circulation, ecology of marine and terrestrial R. organisms, ice sheet dynamics, and atmospheric chemistry and circulation S. a full understanding of glacial-interglacial carbon dynamics
Option 1: PQRS
Option 2: QPRS
Option 3: SPQR
Option 4: SRPQ
Correct Answer: SPQR
Solution : The correct choice is the third option, SPQR.
The sentence begins with the overarching idea (S) that achieving a full understanding of glacial-interglacial carbon dynamics is essential. Following this, the sentence delves into the specifics of what this understanding entails. The sequence unfolds by
Question : $\triangle \mathrm{ABC}$ is a right-angle triangle at $\mathrm{B}$. If $\tan \mathrm{A}=\frac{5}{12}$, then $\sin \mathrm{A}+\sin \mathrm{B}+\sin \mathrm{C}$ will be equal to:
Option 1: $1 \frac{5}{13}$
Option 2: $2 \frac{4}{13}$
Option 3: $3 \frac{1}{13}$
Option 4: $2 \frac{1}{13}$
Correct Answer: $2 \frac{4}{13}$
Solution : Given, $\tan\mathrm{A}=\frac{5}{12}$ Using Pythagoras theorem, $AC^2 = AB^2+BC^2$ ⇒ $AC^2 = 5^2 + 12^2$ ⇒ $AC^2 = 25 + 144$ ⇒ $AC^2 = 169$ ⇒ $AC = 13$ units ⇒ $\sin \mathrm{A} = \frac{5}{13},$ $\sin \mathrm{B} = 1$ and $\sin\mathrm{C} = \frac{12}{13}$ So, $\sin
