Question
Consider the following statements about space
exploration: 1. The James Webb Space Telescope is designed to observe the infrared universe. 2. Chandrayaan-2 successfully landed on the Moon. 3. SpaceX is the first private company to send astronauts to the International Space Station (ISS). Which of the above statements are correct?Solution
The James Webb Space Telescope observes the infrared universe (statement 1). Chandrayaan-2’s lander crash-landed (statement 2 is incorrect). SpaceX sent astronauts to the ISS in 2020 (statement 3).
40.02% of 1220.05 = ?2 + 29.09 × 7.99
766/51 ÷ 387/42 × 121/13 = ?
12.99% of 499.99 ÷ 13.17 = ? ÷ 20.15
(129.98% of 8460) + (119.899% of 8640) = (130.009% of 15820) + ?
26.11% of ? – 521.02 = 648.51
What approximate value should come in the place of question mark (?) in the following questions?
41.99 x 22.01 ÷ √49.01 + ? = 13.99²
(29.98% of 9840) + ? + (19.899% of 8490) = 7560
(3/7 of 1049.88 + 44.95% of 799.79) ÷ (√168.89 + 24.77% of 400.11) = ?
233.98 + 73 × √35.95 - ? = 275.94 ÷ 3.99
