(a) 2000
(b) 500
(c) 250
(d) 1000

Solutions

S1. Ans.(d)
Sol. Given, Rate of interest (i) = 6%
Year’s purchase (Y.P) = ?
Y.P.=100/(i%)
=100/6
= 16.67%

S2. Ans.(d)
Sol.

Pigment	Color
Zinc oxide	White
Copper sulphate	Green
Red lead	Red
Indigo	Blue
Burnt Siena	Brown
Cobalt oxide	Blue

S3. Ans.(b)
Sol.
” RL at point ” A (RL_A )=100m
” BS at point ” A=2.455m” .”
FS” at point ” B=2.745m” .”
RL” at point ” B(RL_B )=?
∑BS-∑FS=” Last ” RL-” first ” RL
2⋅455-2⋅745=RL_B-100
RL_B=99.71m.

S4. Ans.(a)
Sol.

Sight distance	Height of driver above carriage way	Height of object
SSD	1.2m	0.15m
OSD	1.2m	1.2m
ISD	1.2m	1.2m

S5. Ans.(b)
Sol.
Water distribution efficiency = (1-y/d)×100
d= Average depth of water stored in the root zone
y = Average numerical deviation in depth of water stored in the root zone.

S6. Ans.(b)
Sol. According to IS 10500:2012, the acceptable limit of total dissolved solids in drinking water is 500 mg/l and cause for rejection is 2000 mg/l.
