Question
In this question, three statements are given, followed
by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follows/follow from the statements. Statements: All slates are books. Some books are paper. Some paper are boards. Conclusions: I. Some books are slates. II. All books are paper. III. Some boards are paper.Solution
All slates are books (A) β Conversion β Some books are slates (I). Hence conclusion I follows. Some books are paper (I) β I.I. β No conclusion. Hence conclusion II does not follow. Some paper are boards (I) β Conversion β Some boards are v (I). Hence conclusion III follows.
40% are the passing marks. A student gets 250 marks yet fails by 38 marks. What is the maximum marks?
42% of 400 + 38% of 800 + ?2 = 728
β11025 x β5625 - (50)Β² = (?) + (73)Β²
5555 Γ· 11 Γ· 5 = 100 + ?
(-251 × 21 × -12) ÷ ? = 158.13
- Determine the value of following expression:
[{(148 + 32) Γ· 9}% x 1350] + 19 135÷ 15 x 19 + 14807 = ? + √3249 - √9604
26% of 950 + 50/3% of 7962 = ?Β Β
The value of 3 Γ 7 + 5 β 6 Γ· 3 β 9 + 45 Γ· 5 Γ 4 β 45 Β is:
