The number of digits `4^9xx5^(17),` when expressed in usual form is a. `16` b. `17` c. `18` d. `19`

(1095)/(1168) when expressed in simplest form is (13)/(16) (b) (15)/(16)(c)(17)/(26)(d)(25)/(26)

A two digit number is such that the product of the digits is 8. When 18 is added to the number, then the digits are reversed. The number is a. 18 b. 42 c. 24 d. 81

The number of odd divisor of the number N=2^(10). 3^5 .7^2, are 16 b. 17 c. 18 d. 20

A 3 -digit number has,from left to right,the digits,a,b and c with a>c.When the number with the digits reversed is subtracted from the original number,the units digit in the difference is 4. The next two digits,from right to left,are 5 and 9( b) 9 and 55 and 4( d) 4 and 5

If log2=0.30103,log3=0.47712, then the number of digits in 6^(20) is a.15 b.16 c.17 d.18

Mahabharata war lasted for __ days. A. 17 B. 18 C. 19 D. 21

The value of the expression x^(4)-17x^(3)+17x^(2)-17x+17 at x=16 is :

The average of a non-zero number and its square is 5 times the number. The number is (a) 9 (b) 17 (c) 29 (d) 295
