ANS : Right Angled triangle

6.Substense bar is an instrument used for :

ANS : Measuring of horizontal distance in undulated area.

7.Rainguage should be preferably be fixed:

ANS: In open space.

8.As per IRC road recommendation, the maximum limit of super elevation for mixed traffic in plain terrain is:

ANS: 1in 15

9. Percentage of free carbon in bitumen is:

 1. If 6 family earing Rs. 3500, Rs.2700, Rs.3000, Rs.2800, Rs.3900, Rs.2100, Find the mean income.

ANS: Rs.3000

(expl : Add all the value and divide by total no of family which is 6 = Rs. 3000)

2. A refrigerator is purchased for Rs.14,355 including sales tax. if the actual cost price of refrigerator is Rs.13,050, find the rate of sales tax in percentage.

ANS: 10%

(expl: Rs.14,355-13,050= Rs.1,305, so 13,050 is actual price ,

13,050/100=130.5 , which is 130.5*10%= RS.1305 so this is the answer)

3. The difference b/w C.I & S.I for two years on a sum of money lent at 8% p.a. is Rs.40. Then the sum of money lent is 

ANS: 6,250

(expl: 

 S.I=P*R*T/100 ; C.I.= P{1+(r/100)^(2)}-1)

P= Principle amount ;R= Rate of interest ;T= Time period

Difference = C.I-S.I=Interest Amount
