Explanation :

Music instructor takes session from 12 noon to 4:00 pm on Monday, Thursday and Sunday.

Sessions of dance instructor are scheduled between 10:00 am to 2:00 pm. on Tuesday, Thursday, Wednesday and Sunday.

Painting instructor takes sessions between 9:00 am to 12:00 noon on Tuesday, Friday and Thursday and between 2:00 pm to 4:00 pm on Wednesday, Saturday and Sunday.

∴ The dance and painting sessions are simultaneously held on days common to the sessions held by dance instructor between 10:00 am to 2:00 pm and the sessions held by the painting instructor between 9:00 am and 12:00 noon i.e. Tuesday and Thursday.

Hence, option 3.

Answer: Option D

Explanation :

A normal year has 52 weeks and 1extra day.

∴ 365 = 52 × 7 + 1

A leap year has 52 weeks and 2 extra days.

∴ 366 = 52 × 7 + 2

There are 30 extra days between 1971 and 2001.

In this period there were 8 leap years, therefore another 8 extra days.

∴ 38 = 7 × 5 + 3

∴ We are left with 3 extra days.

If 9/12/2001 is a Sunday, then 12/12/1971 was a Sunday and 9/12/1971 was a Thursday.

Hence, option 4.
