Question
Statements: All trollies are pulleys.
> All chains are pulleys. All pulleys are bells. Conclusions: I. All trollies are bells. II. At least some bells are chains. Directions (Q.16-20): In each of the questions below are given two/three statements followed by two conclusions numbered I, and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of given conclusions logically follows from the given statements disregarding commonly known facts.Solution
All trollies are pulleys (A) + All pulleys are bells (A) ⇒ All trollies are bells. Hence, conclusion I follows. All chains are pulleys (A) + All pulleys are bells (A) ⇒ All chains are bells (A) ⇒ conversion ⇒ Some bells are chains. (I). Hence, conclusion II follows.
What approximate value should come in the place of (?) in the following questions?
42.98% of 849 + 18.45% of 1201 ≈ ?(1550.23 ÷ 30.98) + (864.32 ÷ 23.9) + 1724.11 = ?
Find the ratio of the area of an equilateral triangle of side ‘a’ cm to the area of a square having each side equal to ‘a’ cm.
72.8% of (215.69 + 189.38) - 5.97² + (3.01 of 7.8) = ? of (64.02 - 38.95)
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
245.67 + 20.05² + ?³ = √961.89 * 34.02
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
? + 539.76 ÷ 5.4 × 94.80 = 9829.54
(14.98% of 319.99) - 7.998 = √?
