Explanation:

A=1,B=2,C=3--------z=26
so now B+C+D= 2+3+4=9
A+E+C = 1+5+3 = 9
So, F+A+? = 9
=> 6+1+? = 9

Two goats are tied with a rope of length 40m outside of a rectangular shed of dimensions 50m X 30m. The goats are tied to different corners which lie on the opposite ends of a diagonal of the shed. What is the area in which the two goats can eat grass, if they choose not to eat in the common approachable area?

A1200pi

B1225pi

C2400pi

D2450pi

| | Important Formulas | Topic: | Asked In Mu-Sigma |

Explanation:

Given rope of length = 40m (radius)
Area of semi circle =(pi*r^2)/2 = (1600 * pi)/2 = 800*pi ---(1)
Area of quarter circle = (1/2 * 800 * pi) = 400*pi ----- (2)
Area of sector is = r*r*(pi/2)/2 = 25*pi ----- (3)
By adding above eq. (1) (2) & (3)
Total area = 1225*pi
As per quesiton there are 2 goats
so area = 1225*pi*2 = 2450pi

Choose the correct option.

In a society of 80 resident families who subscribe newspapers, 60% of them subscribe The Hindu newspaper, 80% of them subscribe regional language newspaper and 70% of them subscribe TOI. How many families could, at the least, be subscribing to all the three newspapers

A0%

B5%

C10%

D20%

| | Important Formulas | Topic: | Asked In Mu-Sigma |

Explanation:

Total no. of families who take newspaper=80
Hindu newspaper = 60% = (80*60/100) = 48
Regional newspaper = 80% = (80*80/100) = 64
TOI newspaper = 70% = (70*80/100) = 56
Find common families take H.C.F (48,64,56) = 8
Therefore,(8/80)*100=10%
So, common families who take all newspaper = 10%.

A father is 30 years older than his son however he will be only thrice as old as the son after 5 years what is father's present age ?

A40 yrs

B30 yrs

C50 yrs

DNone of these

| | Important Formulas | Topic: | Asked In Mu-Sigma |

Explanation:

Lets assume son's age = x
So, father's age = x + 30

After 5 years:
Son's age = x + 5
Father's age = x + 35

In 5 years the father is thrice as old as his son so:
3(x + 5) = x + 35
x = 10

So, current father's age = 40 Years.

Choose the correct option.

A person travels in a car with uniform speed. He observes the milestone,which has 2 digits. After one hour he observes another milestone with same digits reversed. After another hour he observes another milestone with same 2 digits separated by 0. Find the speed of the car?

A40 Kmph

B55 Kmph

C50 Kmph

D45 Kmph

| | Important Formulas | Topic: | Asked In Mu-Sigma |

Explanation:

Let 10'splace digit is x and unit's place digit y

First milestone : 10x+y
Second milestone : 10y+x
Third milestone: 100x+y

Since the speed is uniform so
Distance covered in first Hr = Distance covered in Second Hr
(10y+x)-(10x+y) = (100x+y)-(10y+x)
By solving,
y=6x
but since x and y are digits so only possible combination is x=1 and y=6,
So average speed = 45 Kmph

If log 0.317=0.3332 and log 0.318=0.3364 then find log 0.319 ?

A0.3396

B0.4396

C0.5396

DNone of these

| | Important Formulas | Topic: | Asked In Mu-Sigma |

Explanation:

log 0.317=0.3332 and log 0.318=0.3364
then
log 0.319=log0.318+(log0.318-log0.317)
=0.3396

A1st Way Group 1: F, J, G, N Group 2: M, N, H, L 2nd Way Group 1: F, J, M, K Group 2: G, K, H, L

B1st Way Group 1: F, J, G, N Group 2: M, K, H, L 2nd Way Group 1: F, J, N, K Group 2: G, N, H, L

C1st Way Group 1: F, J, G, N Group 2: M, K, H, L 2nd Way Group 1: F, J, M, K Group 2: G, N, H, L

DNone of these

| | Topic: | Asked In Mu-Sigma |

Explanation:

8 people namely F,G,H,J,K,L,M,and N respectively.
Now we have to form 2 groups
1st condition: F will always go with J
Meaning: F and J always lie in same group. ............(i)
2nd condition:G and M will never go together.
Meaning: G and M always lie in different groups. .........(ii)
3rd condition:H will always go with L.
Meaning:H and L always lie in same group. .............(iii)
4th condition:N will always go with G.
Meaning:N and G always lie in same group. ..........(iv)
According to (i),(ii),(iii),and (iv)
2 groups can be formed in following 2 ways

1st Way
Group 1: F, J, G, N
Group 2: M, K, H, L

2nd Way
Group 1: F, J, M, K
Group 2: G, N, H, L
