Question
AstroSat, India’s dedicated space observatory, studies
celestial bodies in which spectral bands?Solution
Launched by ISRO, AstroSat is equipped to observe the universe in the ultraviolet, optical, and X-ray spectrum, contributing significantly to the understanding of celestial phenomena and astrophysical processes.
?% of 320 - 69 = 123
5/13 × 104 + 1(2/9) × 198 = 133 + ?
45% of 360 - 160 + ? = √324
Determine the simplified value of following expression:
0.998 + 0.882 + 0.12Â
- What will be come in place of (?) in the given expressions.
(3/4 of 480) – (2/5 of 350) = ? 18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?
- Simplify:

What will come in the place of question mark (?) in the given expression?
16 X ? + 750 ÷ 3 = 60 X 9 + 110
(1225/25) - (192/96) + (50/5) = ?
What will come in place of (?) in the given expression.
25% of 160 + 15% of 200 = ?
