Answer 2

Answer:

Day on 3rd March = Monday

Then Monday will fall on the multiples of 7 from 3rd march

a). 13th August

Number of days from 3rd march to 13 august = 163 days

163 days = 7 × 23 + 2

+2 indicates 2 days next to Monday that is Wednesday

So, 13th August will be Wednesday

b). 25th September

Number of days from 3rd march to 25 September = 213 days

213 days = 7 × 30 + 3

+3 indicates 3 days next to Monday that is Thursday

So, 25th September will be Thursday

c). 22nd July

Number of days from 3rd march to 22 July = 141 days

141 days = 7 × 20 + 21

+1 indicates 1 day next to Monday that is Tuesday

So, 22nd July will be Tuesday
