Options- A. 126.631
- B. 62.069
- C. 72.089
- D. 132.788
- Correct Answer
- 72.089
Explanation534.596 + 61.472 ? 496.708 = ? + 27.271
596.068 ? 496.708 = ? + 27.271
? = 99.36 ? 27.271
? = 72.089.

Correct Answer: 30.25
Explanation:
= (69x85/3x100) + 10.7
= 30.25.
Correct Answer: (1 - 2cos2A)/(sinA cosA)
Correct Answer: -2
Correct Answer: 2cos[(C+D)/2]cos[(C-D)/2]
Correct Answer: 80
Correct Answer:
Explanation:
504/42 × 7 - 63 + 28 = 84 ? 63 + 28 = 49
Hence option 5 is correct.
Correct Answer: 846
Explanation:
(150 x 460)/100 + (24 x 650)/100
= 690+156
= 846
Correct Answer: 12
Explanation:
By replacing the ??? with ?x?
(12.5×14÷8.75) x (100/100) + 42 = 50 + X
(125*140)/875 + 42 = 50 + X
140/7 + 42 = 50 + X
20 + 42 = 50 + X
62 = 50 + X
X = 62 - 50
X = 12
Correct Answer: 3x + 5y = 12
Correct Answer: 3
Explanation:
Ans.
25% of 84 ÷ 7 = ?
[(25 × 84)/100]÷ 7 = ?
21÷ 7 = ?
? = 3
