common factor is 5,10

SORRY THE ANSWER IS A

Common factor is 5,10

common factors are 5 and 10

answer is 10 and 5

actually,they are asking which one has the same relationship as 40 and 70 which is 10 and 40 so, B is the correct answer

common factor is 5,10

Common factors are 5 and 10 ie option B

Sorry I wanted to type option number A.

The common factors of 40 and 70 are 2,5 and 10 which are same as common factors of 10 and 40. (2,5,10) and hence answer B is correct.

Shilpa_Age = 4* Raj_Age --- (1) Riya_Age = Raj_Age - 6 --- (2) Shilpa_Age + Raj_Age + Riya_Age = 72 This can be rewritten as, (from (1) and (2)) 4*Raj_Age + Raj_Age + Raj_Age - 6 =72 6*Raj_Age = 78 Raj_Age = 78/6 = 13 Therefore, Shilpa_Age = 4*13 = 52 Riya_Age = 13 - 6 = 7 Therefore, Shilpa is 52 - 7 = 45 years elder than Riya Option (B)

Riya is younger to Raj therefore she is also younger to Shilpa. let Raj be 'x' . Shilpa = 4x and Riya is x-6. {x+ 4x + x-6 = 72} or 6x - 6 =72 or 6x = 78 or x= 13

yes i am too getting 45.

Answer: D
Solution
Let age of Shilpa, Raj and Riya be S, R, and Ri respectively
Then
S = 4R
Ri = R - 6
S + R + Ri = 72
or
4R + R + R - 6 = 72
6R = 66
R = 11
S = 44
Ri = 5
So Shilpa is (44- 5) 39 years older than Riya

The step written by you 4R + R + R - 6 = 72 6R = 66 This step is wrong. As 6 will be added to 72 and NOT SUBTRACTED. hence, 6R = 78

Raj's age = x. x + 4x + ( x - 6 ) = 72, or 5x + ( x - 6 ) = 72, or 5x + x - 6 = 72, or 6x - 6 = 72, or 6x = 72 + 6, or 6x = 78 or x = 78/6 or x = 13, so Raj is 13 years old. Shilpa is 13 x 4 = 52 years old. Riya is 13 - 6 = 7 years old. Shilpa is 52 - 7 = 45 years older than Riya, so answer is B.

let Raj be = x yrs, Shilpa = 4x, Riya = x-6 therefore x + 4x + x-6 = 72 or 6x = 78 or x = 13 This means Raj = 13 yrs, Shilpa = 4 x 13 = 52 yrs, and Riya = 13 - 6 = 7yrs thus Shilpa is 45 yrs older to Riya (52-7 = 45)

45 years

so many

Ans is A Factors of 36 & 96 are 2,3,6 &12 from the above three numbers are multiples of 3 i.e 3, 6, 12

Answer : A
Solution
3,6,12 are three common factors of 36 and 96 which are also multiple of 3.
Hence the answer is 3 numbers.
The questions is 'how many numbers' and not 'which numbers'.

No,its 3. The common factors are 1,2,3,4,6,12. But the factors that are also multiples of 3 are 3, 6 and 12

Answer : A Solution 3,6,12 are three common factors of 36 and 96 which are also multiple of 3. Hence the answer is 3 numbers. The questions is 'how many numbers' and not 'which numbers'.

factors of 36 are 1,2,3,4,6,9,12,18,36 factors of 96 are 1,2,3,4,6,8,12,24,32,48,96 common 1,2,3,4,6,12 multiple of 3 - 3,6,12 ans is A

Answer : A
Solution
3,6,12 are three common factors of 36 and 96 which are also multiple of 3.
Hence the answer is 3 numbers.
The questions is 'how many numbers' and not 'which numbers'.

I think that 3 and 6 both are factors of 36 and 96 and multiple of 3

3

The correct answer must Hospital as 3/4 turn clockwise takes to the Cinema and Hospital is opposite of the Cinema. The answer will cinema if she takes anticlockwise turn instead of clockwise

cinema hall

may i please know how cinema hall is anti clockwise

ACCORDING TO ME THE ANSWER SHOULD BE 3144 m,SINCE, 1300 m 272 m = 1572 m and 1572 m *2= 3144 m.PLEASE CHECK THE ANSWER.

3/10 is correct

It is 3/20 because- if you add 2/8 and 3/5 =17/20 which he drank =20/20-17/20=3/20

3/10

3/20 is correct

2/8 (=10/40) in the morning left only 6/8 3/5 of 6/8 = 18/40 leftover milk is = 1-(10/40) - (18/40) = 12/40 = 3/10

blah blah blahwhatever

Answer : B
Milk left for the evening = 1 - 2/8 = 6/8
Milk consumed in the evening = 3/5 of 6/8 = 3/5 x 6/8 = 18/40
Total milk consumed = 2/8 + 18/40 = 28/40
Milk left = 1 -28/40 = 12/40 = 3/10

3/20Thank you Priti Srivastav

3/10

3/20

Answer is option B or 3/10

the correct answer is 3/20 which is C

I think they are asking for the mass of all 5 balls together. The mass of small ball is 6 Kg. Hence the total mass = 12 + 6 + 6 + 6 + 6 = 36.

Answer: C (36 kg)
The option C should be 36 kg and not 30 kg. Corrected the mistake.

Solution:
Let the weight of the small ball be x.
3x = 12 + x
2x = 12
x = 6
Weight of 5 balls = 12 + 6+ 6+ 6 +6 = 36kg

left side weight is 12 + 6(small ball) = 6 + 6 + 6 ( which means 12 + 6 + 6 + 6 + 6 = 36)

Answer: C (36 kg)
The option C should be 36 kg and not 30 kg. Corrected the mistake.

Solution:
Let the weight of the small ball be x.
3x = 12 + x
2x = 12
x = 6
Weight of 5 balls = 12 + 6+ 6+ 6 +6 = 36kg
