Helen went to the stationers and bought things worth Euro 45, out of which 30 paise went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items? | [
"None",
"Euro 15.7",
"Euro 15",
"Euro 39.7"

On dividing a number by 5, we get 3 as remainder. What will the remainder when the square of the this number is divided by 5 ? | [
"4 Remainder",
"0 Remainder",
"1 Remainder",
"2 Remainder"
] | A | EXPLANATION
Let the number be x and on dividing x by 5, we get k as quotient and 3 as remainder.
x = 5k + 3
x2 = (5k + 3)2
= (25k2 + 30k + 9)
= 5(5k2 + 6k + 1) + 4
On dividing x2 by 5, we get 4 as remainder.
Remainder = 4

In the faculty of Reverse-Engineering, 226 second year students study numeric methods, 423 second year students study automatic control of airborne vehicles and 134 second year students study them both. How many students are there in the faculty if the second year students are approximately 80% of the total? | [
"666",
"644.",
"515",
"545"
] | B | Solution : Total number of students studying both are 423 + 226 - 134 = 515 (Subtracting the 134 since they were included in the both the other numbers already).
So 80% of total is 515, so 100% is approx. 644.
