The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3     AND  ( - t - 37 ) ≤ 3
t ≤ 3 +
37              
- t + 37 ≤ 3
t ≤
40                    
- t ≤ 3 - 37
                             
- t ≤ - 34   / *( - 1 )
                               
t ≥ 34

Answer:
x<13
Step-by-step explanation:
 
        
             
        
        
        
If two angles are complimentary then their sum would equal to 90 degree.
i.e., x + 3x + 30 = 90
4x = 90 - 30
x = 60 / 4
x = 15
In short, Your Answer would be Option A
Hope this helps!
        
                    
             
        
        
        
1 is wrong there are two numbers greater than 4 but less than or equal to 6. 
 the first one was correct
        
             
        
        
        
The cash payment for the article is RS. 2,260. 
A discount reduces the price of an item. The article becomes cheaper after the discount. 
Cost of the article after the RS. 20 discount = RS. 2020 - 20 = RS 2000
VAT means value added tax. VAT increases the price of an item. The cost of the article increases by 13% after the  VAT is levied, 
Cost of the article = (100 + 13%) x 2000 
1.13 x 2000 = RS 2,260.
