Number, Ranking and Time Sequence Test Questions and Answers

Answer: B

There are 119 girls behind her.

With 150 students in the ratio 1 : 5, there are 25 boys and 125 girls. Saranya has 5 girls in front of her, and she herself is a girl:

\[ 125 - 5 - 1 = 119 \]

Her overall position (22nd) is not needed, since only girls are counted. 145 counts every student except the 5 girls in front, and 150 is the whole class; 109 does not follow from the counts.

Answer: A

The heaviest person is P.

R is heavier than exactly three people, so R is second heaviest. Q is lighter than R but heavier than S, and S is heavier than T, so T is the lightest (which agrees with 'S is not the lightest'):

\[ ? > R > Q > S > T \]

The only person left for the top place is P. R is second, not first, and Q and T are lower down.

Answer: C

The tallest is Vijay.

Only Maria is shorter than Suresh, so Maria is the shortest and Suresh is second shortest. That leaves Fathima and Vijay as the two tallest, and since Fathima is shorter than Vijay, Vijay is the tallest.

The order from shortest is Maria, Suresh, Fathima, Vijay. Suresh and Maria are near the bottom, and Fathima is shorter than Vijay, so none of them can be the tallest.

Answer: A

Correct answer: Friday

From 25 June to 15 August is \( 5 + 31 + 15 = 51 \) days. Since \( 51 = 49 + 2 \), the day moves on by two from Wednesday, giving Friday.

Answer: D

Correct answer: 6 : 34

In each pair the second number is the square of the first plus two: \( 4^2+2 = 18 \), \( 7^2+2 = 51 \), \( 9^2+2 = 83 \). For 6 the rule gives \( 6^2+2 = 38 \), not 34 - so 6 : 34 is the odd pair.

Answer: A

Correct answer: 111

Counting both end dates: 6 days of January (26th to 31st), 29 of February 2008 - a leap year - 31 of March, 30 of April and 15 of May: \[ 6 + 29 + 31 + 30 + 15 = \mathbf{111} \]

Answer: C

Correct answer: 28

Three people stand ahead of C, so C is 4th. Eight people separate B from C, putting B at the 13th place, and five separate A from B, with A ahead of B at the 7th place. Twenty-one people stand behind A, so the queue holds \[ 7 + 21 = \mathbf{28} \]

Answer: D

Correct answer: 0

Every multiple of 9 is also a multiple of 3, since \( 9 = 3 \times 3 \). So no number whatever can be divisible by 9 and not by 3, and the count is 0.

Answer: A

Correct answer: 1

Interchanging the 1st with the 6th, the 2nd with the 7th and so on turns 2796543018 into 4301827965. Reading off the place the question asks for gives 1.

Answer: D

Correct answer: thursday

If the 4th is a Tuesday, the 24th is twenty days later, and \( 20 = 14 + 6 \), so it falls six days on from Tuesday - a Monday. Three days after that is the 27th: Thursday.
