The digit in the tens place of a two digit number is 3 more than the
digit in the units place. Let the digit at units place be b. Then the
number is
(a)11b + 30 (b) 10b + 30 (c) 11b + 3 (d) 10b + 3
A linear equation in one variable has

If a and b are positive integers, then the solution of the equation
ax = b has to be always
(a) positive (b) negative (c) one (d) zero
The value of x for which the expressions 3x – 4 and 2x + 1 become equal is
