E) If 19th June 2023 is Monday, which day of the week was 30th April 2023?

• Monday

• Sunday

• Tuesday

• Saturday

Answer explanation

Solution: Working backwards, from June 18th to June 1st, there are 18 days.
The month of May has 31 days.
Adding 1 day because we need to find April 30, it has 32 days.
Getting the total number of days, 18 + 32 = 50. Then, 50 ÷ 7 = 7 remainder 1.
Using the remainder, counting the day before Monday is Sunday.

E) According to the pattern shown below, what should be the English letter filled in the blank?
V, A, T, D, R, G, __, …

• S

• R

• P

• Q

Answer explanation

Solution:
By observation, we can group the letters into two patterns: (V, T, R,…) and (A, D, G, …). Since the blank is in the (V, T, R, …) group, we can start focusing there.
Letters V, T, and R represent the order in the alphabet: 22, 20, and 18.
The pattern is 22 − 2 = 20, 20 − 2 = 18.
So, the next one should be 18 − 2 = 16.
The 16th letter of the alphabet is P.

E) Felix is counting numbers from 5. Whenever the number is a multiple of 4 or a multiple of 6, he claps his hands one time. What will be the next number counting after Felix clapping his hand 11 times?

• 40

• 37

• 38

• 39

Answer explanation

Solution: The multiples of 4 starting from 5 are: 8, 12, 16, 20, 24, 28, 32, 36, 40, ...
The multiples of 6 starting from 5 are:
6, 12, 18, 24, 30, 36, ...
Combining the two, we have:
6, 8, 12, 16, 18, 20, 24, 28, 30, 32, 36, where 36 is his 11th clap.
Thus, the next number is 37.

D) Priya and sister have 31 and 29 coins respectively. Mother gives each of them 2 coins every day. What is the sum of the number of coins between Priya and sister 3 weeks later?

• 144

• 145

• 414

• 441

Answer explanation

Solution: Each of them will receive 2 coins everyday, so a total of 4 coins will be given every day. 1 week is 7 days, so 3 weeks is 21 days. Thus, 4×21=84. Adding the coins that Priya and sister have initially, 84 + 31 + 29 = 144.
