Question
Statements: All doors are nuts. All
nuts are bolts. All bolts are metals. Conclusions: I. Some metals are nuts II. Some bolts are not doors. III. Some metals are doors. (Q.156-160): In each of the questions below are given three statements followed by three conclusions numbered I, II and III. 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 nuts are bolts.(A) + All bolts are metals. (A) = All nuts are metals (A) ⇒ conversion ⇒ Some metals are nuts.(I), Hence, conclusion I follows. All doors are nuts.(A) + All nuts are bolts.(A) = All doors are bolts. (A) All doors are bolts. (A) + All bolts are metals.(A) = All doors are metals.(A) ⇒ conversion ⇒ Some metals are doors. (I), Hence, conclusion III follows.
A man purchases some pens at a rate of 4 for βΉ14 and an equal number at a rate of 5 for βΉ18. He sells all the pens at a rate of 6 for βΉ20. What is...
What will come in the place of question mark (?) in the given expression?
30% of 50% of 1200 = 18/11 Γ ?
- What will be come in place of (?) in the given expressions.
(58% of 250) + (42% of 150) = ? The value of 5Β³ Γ 5β΄ Γ 5Β² = ?
20.05% of 220.05 β 15.15% of 99.99 Γ 2.02 = ?
What will come in the place of question mark (?) in the given expression?
250% of...
(24% of 500 - 20)Β Γ· 25 = ?Β Γ· 4
Simplify the following expression:-
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
β 225 x 24 - β 144 x 18 = ?
