Directions (1-5):  Read both the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. Give answer— (1) if only conclusion I is true. (2) if only conclusion II is true. (3) if either conclusion I or conclusion II is true. (4) if neither conclusion I nor conclusion II is true (5) if both conclusions I and II are true.Solution
Alternate solution: Some novels are newspapers (I) + No newspaper is a magazine (E) `->` Â Some novels are not magazines(O). Hence conclusion I does not follow. Some books are novels(I) + Some novels are newspapers(I) `->` Â [Probable conclusion]Â `->` Â Some books are newspapers(I) [Probable conclusion] `->` Â All books can be newspapers(A). Hence conclusion II follows.
(2197)1/3 + (18)2 − 121 = ? − 69 × 5
Solve the following equation.
143 + 14.3 + 1.43 + 0.143 + 0.0143 =?
Simplify the following expression:
(√121 + √196) × 7 =? × 5
- What will come in the place of question mark (?) in the given expression?
62.5% of 120 + ? = (720 + 90) ÷ √36 (54/6) × 5 + 12 × (17/2) = ?% of 700
What is the value of 7/9-11/12+12/16-1/8?
- What will come in the place of question mark (?) in the given expression?
40% of (320 ÷ 4) + 2² X 25 = ? + 42 (13)2 - 3127 ÷ 59 = ? x 4
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
