Q1

For Questions 951–955, consider four schemes P, Q, R and S. Their sanctioned budgets are ₹800 crore, ₹1200 crore, ₹1500 crore and ₹1000 crore respectively. The percentages actually spent are 75%, 80%, 72% and 90% respectively. Of the amount spent, 40%, 50%, 45% and 60% respectively is spent on infrastructure. What is the total amount actually spent by all four schemes?

प्रश्न 951–955 के लिए चार योजनाओं P, Q, R और S पर विचार कीजिए। उनकी स्वीकृत बजट राशि क्रमशः ₹800 करोड़, ₹1200 करोड़, ₹1500 करोड़ और ₹1000 करोड़ है। वास्तव में खर्च की गई राशि क्रमशः 75%, 80%, 72% और 90% है। खर्च की गई राशि में से क्रमशः 40%, 50%, 45% और 60% अवसंरचना पर खर्च होती है। चारों योजनाओं द्वारा वास्तव में खर्च की गई कुल राशि कितनी है?

  1. ₹3440 crore₹3440 करोड़
  2. ₹3540 crore₹3540 करोड़
  3. ₹3640 crore₹3640 करोड़
  4. ₹3740 crore₹3740 करोड़
Check answer
Answer: ₹3540 crore / ₹3540 करोड़

Actual expenditure: P=800×75%=600; Q=1200×80%=960; R=1500×72%=1080; S=1000×90%=900. Total=600+960+1080+900=₹3540 crore.
