= Sunday

Q3. What Day Of The Week Was 1 January 1901?

1 Jan 1901 = (1900 years + 1st Jan 1901)

We recognize that quantity of unusual days in four hundred years = 0

Hence the number of unusual days in 1600 years = 0 (Since 1600 is an excellent a couple of of 400)

Number of ordinary days in the duration 1601-1900

= Number of unusual days in 300 years

= 5 x 3 = 15 = 1

(As we will reduce best multiples of seven from extraordinary days with out affecting some thing)

1st Jan 1901 = 1 unusual day

Total wide variety of strange days = (zero + 1 + 1) = 2

2 bizarre days = Tuesday

Hence 1 January 1901 is Tuesday.

Q24. A Fort Had Provision Of Food For one hundred fifty Men For forty five Days. After 10 Days, 25 Men Left The Fort. Find Out The Number Of Days For Which The Remaining Food Will Last?

Given that citadel had provision of food for 150 men for 45 days

Hence, after 10 days, the remaining food is sufficient for one hundred fifty men for 35 days

Remaining men after 10 days = a hundred and fifty - 25 = a hundred twenty five

Assume that when 10 days,the final food is enough for one hundred twenty five men for xx days

More guys, Less days (Indirect Proportion)

150 : 125 :: x : 35

one hundred fifty×35=125x


X=6×7=forty two.

Q25. If Log10 five + Log10 (5x+1) = Log10 (x+5) + 1, Then X Is Equal To?

Log105 + log10 (5x+1) = log10 (x+five) + 1

=> log105 + log10(5x+1) = log10(x+5) + log10 10

=> log10[5(5x+1)] = log10[10(x+5)]

=> 5(5x+1) = 10(x+5)

=> 5x+1 = 2(x+five)

=> 5x + 1 = 2x + 10

=> 3x = nine

=> x = 3.
