UPSC Prelims 2026 CSAT Paper II · Q70 / 72 Basic Numeracy easy

In a recruitment process, the selection of candidates is based on their performance in three components. The weightages of the components 1, 2 and 3 are 0·2, 0·3 and 0·5, respectively. Use the data given below and find the cutoff score if exactly three candidates are to be selected : Candidate | Score in component 1 | Score in component 2 | Score in component 3 1 | 5 | 4 | 6 2 | 4 | 6 | 5 3 | 3 | 2 | 8 4 | 9 | 4 | 3 5 | 8 | 8 | 2

  1. (a) 5·1 ✓ UPSC's answer
  2. (b) 5·2
  3. (c) 5·3
  4. (d) 5·4

Why the answer is (a)

• Weighted score = 0·2 × C1 + 0·3 × C2 + 0·5 × C3.

• Candidate 1: 1·0 + 1·2 + 3·0 = 5·2. Candidate 2: 0·8 + 1·8 + 2·5 = 5·1. Candidate 3: 0·6 + 0·6 + 4·0 = 5·2.

• Candidate 4: 1·8 + 1·2 + 1·5 = 4·5. Candidate 5: 1·6 + 2·4 + 1·0 = 5·0.

• The top three are 5·2, 5·2 and 5·1, so a cutoff of 5·1 selects exactly three: (a).

Why the other options are wrong

(b) 5·2
A cutoff of 5·2 selects only two candidates.
(c) 5·3
A cutoff of 5·3 selects nobody.
(d) 5·4
A cutoff of 5·4 selects nobody.
