RRB NTPC Graduate CBT 1 23 Jun 2025 Shift 3 – Question Paper

Concept: Unemployment data in usual status (15+ years) comes from the Periodic Labour Force Survey (PLFS), quoted in the Department of Economic Affairs / Economic Survey reports.

1. Urban unemployment rate fell from 5.4% in FY23 (2022-23) to 5.1% in FY24 (2023-24).
2. So the trend was a decrease, ruling out "increased" and "stable".

Yaad rakhein: Urban UR: 5.4% → 5.1%; overall UR (all India, 15+) stayed about 3.2%.

Answer: (A) Decreased from 5.4% to 5.1%

Concept: For 2 years, $\text{CI}=P[{(1+\frac{R}{100})}^2-1]$ and $\text{SI}=\frac{P\times R\times T}{100}$.

1. At $5\%$: $(1.05{)}^2-1=0.1025$
2. $0.1025P=102.5\Rightarrow P=1000$
3. $\text{SI}=\frac{1000\times 5\times 2}{100}=100$

Trick: 2-year CI at $R\%$ = SI $+$ interest on interest: $\text{CI}-\text{SI}=P{\left(\frac{R}{100}\right)}^2$. Here $\text{CI}=\text{SI}(1+\frac{R}{200})$ → $\text{SI}=\frac{102.5}{1.025}=100$.

Answer: (C) ₹$100$

Concept: First swap the signs as told, then solve using BODMAS (÷, × before +, −).

1. Swap: $35+112÷84\times 48-75$
2. $112÷84=\frac{4}{3}$, and $\frac{4}{3}\times 48=64$
3. $35+64-75=24$

Trick: Rewrite the whole expression with the new signs first – mistakes happen when swapping in your head.

Answer: (A) $24$
