I THINK A. IS THE ANS

Any number remains the same on changing their order . There is a rule a * b = b * a . what is wrong ........... I think D is correct

B

common factor is 5,10

Common factor is 5,10

common factors are 5 and 10

common factor is 5,10

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.

SORRY THE ANSWER IS A

Common factors are 5 and 10 ie option B

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

Sorry I wanted to type option number A.

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

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)

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

45 years

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.

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

Answer : D
There was a mistake in option B which has been corrected.

Solution
2 mm = .2 cm
42cm + 2 mm = 42cm + .2cm = 42.2cm

Answer : D
There was a mistake in option B which has been corrected.

Solution
2 mm = .2 cm
42cm + 2 mm = 42cm + .2cm = 42.2cm

I had the same problem. 42.2 cm is given twice in the options and the answer is marked wrong if u choose one of them (I forget which one). Pls rectify this error.

D

Answer : D
There was a mistake in option B which has been corrected.

Solution
2 mm = .2 cm
42cm + 2 mm = 42cm + .2cm = 42.2cm

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

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'.

Answer : A
Solution
3,6,12 are three common factors of 36 and 96 which are also multiple of 3.

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

3

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

so many

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.

may i please know how cinema hall is anti clockwise

cinema hall

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

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.
