The calendar for the year 2015 will be the same for the year:

A
2042

B
2045

C
2040

D
2041

Solution

Count the number of odd days from the year 2015 onwards to get the sum equal to 0 odd days.

No. of odd days from 2015 till 2018 → 1 + 2 + 1 +1 = 5 odd days

No. of odd days from 2019 till 2022 → 5 + 1 + 2 + 1 + 1 = 10 odd days (divided by 7days of a week) = 3 odd days

No. of odd days from 2023 till 2026 → 3 + 1+ 2 + 1 + 1 + = 8 odd days (divided by 7days of a week) = 1 odd days

No. of odd days from 2027 till 2030 → 1 + 1+ 2 + 1 + 1 = 6 odd days

No. of odd days from 2031 till 2034 → 6 + 1+ 2 + 1 + 1 + = 11 odd days (divided by 7days of a week) = 4 odd days

No. of odd days from 2035 till 2038 → 4 + 1 + 2 + 1 + 1 = 9 odd days (divided by 7days of a week) = 2 odd days

No. of odd days from 2039 till 2042 → 2 + 1+ 2 + 1 + 1 = 0 odd days

So, The calendar of 2015 will be similar to 2042.
Question 9

Complete the analogy 40 ∶ 100 ∶∶ 60 ∶ ?

A
230

B
225

C
310

D
325

Solution

The logic is:

40 : 100 → (10 × 4) : 10²

Similarly,

60 : ? → (15 × 4) : 15²

⇒ ? = 225
Question 10
1 / -0.25

Two persons start from the same point S. One travels \(50 ~m\) north and then takes left turn and travels \(15 ~m\) and again takes a left turn and travels \(20 ~m\). The other travels \(40 ~m\) south and takes right turn and travels \(20 ~m\) and again takes a right turn and travels \(30 ~m\). What is the shortest distance between both of them?

A
\(45 \sqrt{5} ~m\)

B
\(30 \sqrt{2} ~m\)

C
\(25 \sqrt{5} ~m\)

D
\(5 \sqrt{65} ~m\)

Solution

According to the directions, the diagram given below can be drawn-

The red line shows the movement of the first person and the black line shows the movement of the second person.

The first person stops at F1 and the second person stops at F2.

The shortest distance between both of them is the distance between F1 and F2. (let \(d\))

According to Pythagoras Law-

\(\Rightarrow d^{2}=40^{2}+5^{2}\)

\(\Rightarrow d^{2}=1600+25\)

\(\Rightarrow d^{2}=1625\)

\(\Rightarrow d=5 \sqrt{65} ~m\)
