Options- A. 48
- B. 49
- C. 50
- D. 51
- Correct Answer
- 50
Explanation1 < 4n + 7 < 200
n can be 0, or -1
n cannot be -2 or any other negative integer or the expression 4n + 7 will be less than1.
The largest value for n will be an integer < (200 - 7) /4
193/4 = 48.25, hence 48
The number of integers between -1 and 48 inclusive is 50

Correct Answer: 7 + 817/1020
Explanation:
=> =>
Correct Answer: 99940
Correct Answer: 170 cr
Explanation:
Property value of Mugilan x
130 × 3 = x + x + 20 + x + 20 + 50
390 = 3x + 90
3x = 300
X = 100
Anitha = 100 + 20 + 50 = 170
Correct Answer: 125
Correct Answer: 144
Correct Answer: increase to more than double
Explanation:
The best approach is to pick a number that satisfies the rules that x and y are greater than 0. So for example you could choose 25 for y.
The value of x before doubling is then 25 - 50/25 = 23
The value after doubling y will be 50 - 50/50 = 49, which is more than double.
Correct Answer: A + 5
Correct Answer: 9
Correct Answer: 3
Correct Answer: ?8
