Question
L1 refers to Lagrange Point 1, one of 5 points of the
orbital plane of the Earth -Sun system. In each question below, a sentence is given with a part of it printed in bold type. That part may contain a grammatical error. Each sentence is followed by phrases 1), 2) and 3). Find out which phrase should replace the phrase given in bold to correct the error, if there is any, and to make the sentence grammatically meaningful and correct. If the sentence is correct as it is and ‘ No correction is required’ , mark 4) as the answer.Solution
in the orbital plane of the earth is grammatically correct.
342 – 232 + 256 – 104 = ?
14 × 11 + 25 – ? = 21% of 300
2850 ÷ 2.5 - ? × 42 = 300
What will come in the place of question mark (?) in the given expression?
(72 × 6 ÷ 12) × 6 = ?
Find the value of 325 × 5 + 31 × 21 – 22 × (63 − 52).
√? = 80% of 720 - 22% of 2500
5555 ÷ 11 ÷ 5 = 100 + ?
- What will come in place of (?) in the given expression.
[45 + (36 ÷ 6)] × 2 – 10 = ? (23.95)2 – (25.006)2 + (8.0099)2 – (7.07)2 = ? - (14.990)2
If a³ - b³ = (a - b)(a² + ab + b²), find a³ - b³ when a = 10 and b = 4.
