Q:

What was the day on 15th august 1947 ?

 A) Friday B) Saturday C) Sunday D) Thursday

Answer & Explanation Answer: A) Friday

Explanation:

15 Aug, 1947 = (1946 years + Period from 1.1.1947 to 15.8.1947)

Odd days in 1600 years = 0

Odd days in 300 years = 1

46 years = (35 ordinary years + 11 leap years) = (35 x 1 + 11 x 2)= 57 (8 weeks + 1 day) = 1 odd day

Jan.   Feb.   Mar.   Apr.   May.   Jun.   Jul.   Aug

( 31 + 28 + 31 + 30 + 31 + 30 + 31 + 15 ) = 227 days = (32 weeks + 3 days) = 3 odd days.

Total number of odd days = (0 + 1 + 1 + 3) = 5 odd days.

Hence, as the number of odd days = 5 , given day is Friday.

Q:

If each side of a square is increased by 25%, find the percentage change in its area?

 A) 65.25 B) 56.25 C) 65 D) 56

Answer & Explanation Answer: B) 56.25

Explanation:

let each side of the square be a , then area = a x a

As given that The side is increased by 25%, then

New side = $\inline \fn_jvn \small \frac{125a}{100}$ = $\inline \fn_jvn \small \frac{5a}{4}$

New area = $\inline \fn_jvn \small \left ( \frac{5a}{4} \right )^{2}$

increased area= $\inline \fn_jvn \small \frac{25a^{2}}{16}-a^{2}$

Increase %= $\inline \fn_jvn \small \frac{\left [ \frac{9a^{2}}{16} \right ]}{a^{2}}x100$ % = 56.25%

 A) 48 min. past 12. B) 46 min. past 12. C) 45 min. past 12. D) 47 min. past 12.

Answer & Explanation Answer: A) 48 min. past 12.

Explanation:

Time from 8 a.m. on a day to 1 p.m. on the following day = 29 hours.

24 hours 10 min. of this clock = 24 hours of the correct clock.

$\inline \fn_jvn \frac{145}{6}$ hrs of this clock = 24 hours of the correct clock.

29 hours of this clock = $\inline \fn_jvn (24\times \frac{6}{145}\times 29)$ hrs of the correct clock

= 28 hrs 48 min of the correct clock.

Therefore, the correct time is 28 hrs 48 min. after 8 a.m.

This is 48 min. past 12.

 A) 2.875 B) 3.875 C) 4.875 D) 5.875

Answer & Explanation Answer: B) 3.875

Explanation:

ANS:      log5512 = ${\color{Black}&space;\frac{\log&space;512}{\log&space;5}}$  =  ${\color{Black}&space;\frac{\log&space;2^{9}}{\log&space;(\frac{10}{2})}}$  =${\color{Black}&space;\frac{9\log&space;2}{\log10-\log&space;2&space;}}$ =${\color{Black}&space;\frac{(9\times&space;0.3010)}{1-0.3010&space;}}$ =${\color{Black}&space;\frac{2.709}{0.699&space;}}$ =${\color{Black}&space;\frac{2709}{699&space;}}$ =3.876
