yes i am too getting 45.

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)

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

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

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.

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

45 years

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)

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.

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

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 : 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.
Hence the answer is 3 numbers.
The questions is 'how many numbers' and not 'which numbers'.

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

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

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

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

so many
