A number consists of two digits. If the digits interchange places and the new number is added to the original number, then the resulting number will be divisible by : | [
"11",
"9",
"3",
"13"
] | A | Solution
Let the ten's digit be x and units digit be y. Then, number = 10x + y.
Number obtained by interchanging the digits = 10y + x.
∴ (10x + y) + (10y + x) = 11 (x + y), which is divisible by 11.

A sum of Rs. 2704 is lent into two parts so that the interest on the first part for 8 years at 3% per annum may be equal to the interest on the second part for 3 years at 5% per annum. Find the second sum? | [
"1677",
"1664",
"1698",
"1672"
] | B | (x*8*3)/100 = ((2704 - x)*3*5)/100
24x/100 = 40560/100 - 15x/100
39x = 40560 => x = 1040
Second sum = 2704 – 1040 = 1664

Let's figure out how many 5's are in the prime factorization of 30!
The multiples of 5 are: 5, 10, 15, 20, 5*5, 30.
Thus 5^7 will divide 30! but 5^8 will not.
Clearly 2^7 will divide 30!
