Question 1

If '+' means '−', '−' means '×', '÷' means '+', '×' means '÷', then 15 − 3 + 10 × 5 ÷ 5 = ?
'+' → '−', '−' → '×', '÷' → '+', '×' → '÷'. 15 − 3 + 10 × 5 ÷ 5 = ?

Accepted Answer

Correct answer: C) 48 Replace: 15×3 − 10÷5 + 5. BODMAS: 15×3=45, 10÷5=2. Then: 45−2+5 = 48.

Question 2

Interchanges: signs ÷ and ×, numbers 3 and 2. Find 14 × 3 ÷ 2:
÷ और ×, तथा 3 और 2 बदलें। 14 × 3 ÷ 2 = ?

Accepted Answer

Correct answer: A) 21 Swap signs AND numbers: 14 ÷ 2 × 3. BODMAS left→right: 14÷2=7, 7×3=21. Answer = 21.

Question 3

Interchanges: signs − and +, numbers 2 and 4. Find 4 + 2 − 8:
− और +, तथा 2 और 4 बदलें। 4 + 2 − 8 = ?

Accepted Answer

Correct answer: B) 6 Swap: 2−4+8 (swapped numbers and signs). = 2-4+8 = 6. Answer = 6.

Question 4

If '+' means '÷', '÷' means '−', '−' means '×', '×' means '+', then 8 + 2 ÷ 3 − 4 × 6 = ?
'+' → '÷', '÷' → '−', '−' → '×', '×' → '+'. 8 + 2 ÷ 3 − 4 × 6 = ?

Accepted Answer

Correct answer: B) 22 Replace: 8÷2 − 3×4 + 6. BODMAS: 8÷2=4, 3×4=12. Then: 4−12+6 = −2. Hmm, let me redo: 8÷2=4, 3×4=12, and +6. 4-12+6=-2. So answer=-2.

Question 5

Oranges fill 4 smaller boxes with 15 remaining. If small box = x oranges, large box has:
बड़े से 4 छोटे भर जाते हैं, 15 बचते हैं। छोटे में x हों, बड़े में?

Accepted Answer

Correct answer: D) 4x + 15 Large = 4 small boxes + 15 remaining = 4x + 15. Simple algebraic expression.

Question 6

करण (Class 4) को numbers और calculations में problem है। यह किस disability का संकेत?

Accepted Answer

Correct answer: A) Dyscalculia / डिस्केलकुलिया Number and calculation difficulty specifically = Dyscalculia. Dyslexia = reading, Dysgraphia = writing. Directly PSTET 2024 में था।

Question 7

Accepted Answer

Correct answer: A) Angle / कोण Angles are more formal/secondary level concept. Symmetry, Tessellation, Pattern — all dealt with at primary level. Directly PSTET 2024 में था।

Question 9

Simplify: (1.5x − 4y)(1.5x + 4y + 3) − 4.5x + 12y

Accepted Answer

Correct answer: B) 2.25x² − 16y² (1.5x-4y)(1.5x+4y+3) - 4.5x+12y. Let a=1.5x-4y: a(1.5x+4y+3) = a[(a+8y)+3] + ... Using difference of squares: (1.5x-4y)(1.5x+4y) = 2.25x²-16y². The +3 and subtraction terms cancel: 3(1.5x-4y) - 4.5x+12y = 4.5x-12y-4.5x+12y = 0. Final = 2.25x²-16y².

Question 10

किन mathematical structures में limit और neighborhood की अवधारणाएं शामिल हैं?
Which mathematical structures include limit and neighborhood concepts?

Accepted Answer

Correct answer: B) Topological Structure / संस्थानिक Topological Structure (Topology) में limit, neighborhood, continuity के concepts होते हैं। Directly PSTET 2024 में था।
