1. A sum of money is lent out at CI at 20% p.a for 2 years.It would fetch Rs 1928 more if intrest is compunded half yearly.Find the sum?
Rs 80000
Rs 55000
Rs 85000
Rs 90000
None of these
Option A
Let the sum be P.
Intrest obtained=20+20+20*20/100=44
Intrest on half yearly=10+10+10*10/100=21
Again,21+21+21*21/100=46.42%
Difference=46.42-44=2.42%
2.41%=1928
1%=800
100%=80000

2. How many metal spehere can be made out of solid metal cone of 28 cm high and 6 cm radius,the diameter of each radius is 3 cm?
82
76
74
80
None of these
Option C
Number of spehere=Vol of cone/Vol of each spehere

3. Study the following and answer the questions:

Y=81% of (√680-√480) + 70% of (22.950 + 25.890)

42
35
38
40
None of these
Option C
=81/100 *(26-22)+ 70/100*48.840
=3.24+34.20

Option A
40*1=40
40*0.5=20
20*3=60
60*0.25=5

5. a)x^2-31x+238=0
b)y^2-28y+187=0
x>y
x
x is less thn or equal to y
x is greater than or equal to y

6. Akansha and Brijesh run from Point P to Point Q at distance of 1200 m at 4m/s and 5m/s respectively.Brijesh reaches Y and immeiately turns back meeting Akansha at point R.Wha is the distance from Q to R?
400/3 m
350/3 m
500/3 m
550/3 m
None of these
Option A
When they meet,distance travelled=2*1200=2400 m
Time taken=2400/(4+5)=800/3 sec
Distance of R from P=4*800/3=3200/3 m
Therefore,distance of R from Q=1200-3200/3=400/3 m

7. A metallic spehere of diameter 12 cm is meletd and drwan into a wire of uniform cross-section.If the radius of wire is 2mm,find lenghth?

80 m
81 m
Option B
Vo of metalic spehere=4/3 * n * 6^3
(4/3)*n*6^3 = n *0.2^2 * Lenght
Length=72
