Ans. Shuttering.
Q.14. Chowkhat or frame of the door is measured in ã…¡ã…¡.
Ans. Cubic meter.
Q.15. Calculate the preliminary estimate for a building having a total carpet area of 600 square meters. Extra provision as 10% of the carpet area is provided for walls and verandah. The plinth area rate is Rs. 1,200 per square meter.
Ans. Rs. 7,92,000
Q.16. Calculate the capitalized value of a building having annual rent of Rs. 50,000 and highest rate of interest is 5%.
Ans. Rs.1000000
Q.17. Soundness of cement is tested by ã…¡.
Ans. Le-chatelier apparatus.
Q.18. What is the representative fraction for a scale of 10 cm = 25 km ?
Ans. 1։250000
Q.19. The line which is used to collect the details of the objects in an area is called ―.
Ans. Tie line.
Q.20. The least count of a theodolite is ã…¡.
Ans. 20 seconds.
Hint :
Q.15.Solve.
Total carpet area of building = 600 sqm
Area for walls and varandah = 600ｘ10/100
= 60 sqm
So total area = 600 + 60 = 660 sqm
Preliminary estimate for total Area = 660ｘ1200 = 792000
Q.16.Solve.
Capitalized value of a building
capitalized value = annual income ✖ year's purchase
Year's purchase = 100/rate of interest
= 100/5 = 20
So capitalized value = 50000 x 20 = 1000000
Q.18.Solve. Representative fractions are a unit-less relation.
Between one "unit" on the map and however many "units" of the same type on the ground.
Representative fraction = 10cm/25km
R.F. = 10/(25x1000Ñ…100)
= 10/2500000 = 1/250000
