Question
Answer the questions based on the information given
below: Eight students L, M, N, O, P, Q, R and S scored different marks in an exam. L scored 6 marks more than P. Neither R nor S scored more than P. At least three students scored more than L. Mark scored by O is the average of L and P. Difference between the mark scored by M and O is 10 marks. Q scored more than N, who doesn’t score more than M. Q doesn’t score the second highest mark. R doesn’t score the lowest mark.  What is the mark scored by M, if L scored 28 marks less than Q, who scored 166 marks?Solution
As L scored 6 marks more than P. Neither R nor S scored more than P. At least three students scored more than L. Mark scored by F is the average of L and P. Difference between the mark scored by M and O is 10 marks. Q scored more than N, who doesn’t score more than M. Q doesn’t score the second highest mark. R doesn’t score the lowest mark, so Q > M > N > L > O > P > R > S Mark scored by L = (166 – 28) = 138 Mark scored by O = (138 + 132)/ 2) = 135 Mark scored by M = (135 + 10) = 145
- What will come in place of the question mark (?) in the following questions?
300−40% of 200=? - Simplify the following expression:
16 + [17 - (8 + 11) + 6 - 3] ÷ 0.2 Simplify the following expression.
(3-3 × 3 + 3 ÷ 3 + 3 × 5) × 2 of 5 + (2 + 2 ÷ 2 + 2 × 2 - 2)
2/9 of 5/8 of 3/25 of ? = 40
115 ÷ 23 + 12 × 6 = ? + 16 - 35
√? = 32% of 900 + 48% of 50
 Â
5/13 × 104 + 1(2/9) × 198 = 133 + ?
Simplify the following expressions and choose the correct option.
40% of 360 + 25% of 248 - 30
(11/12) × (18/22) × (4/3) + 3 = ?2
[(15)³ × (8)²] ÷ (90 × 6) = ?²
