Question
Read the given statements and conclusions carefully.
Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusion(s) logically follow(s) from the statements. Statements: All cliffs are hills. No cliff is valley. Conclusions: (I) : Some hills are cliffs. (II) : No hill is a valleySolution
All cliffs are hills (A) β Conversion β Some hills are cliffs (I). Hence conclusion I follows. Some hills are cliffs (I) + No cliff is valley (E) β Some hills are not valley (O). Hence conclusion II does not follow.
What will be the value of expression if the signs β(+)β and β(Γ)β are interchanged?
63 + 7 Γ· 21 Γ 14 β 24 Γ· 6
...Which two signs should be interchanged in the following equation to make it correct:
640 Γ· 80 + 6 Γ 20 β 10 = 58
Which two signs should be interchanged in the following equation to make it correct ?
132 Γ 11 + 8 β 3 Γ· 12 = β16
