1) B (23 yrs) Father= X Mother= 24+13(ena) =37 present age Mother is 3yrs younger than father so father would be 40 , 37+3=40 Then marriage age of father would be 40-(13+4 ) =23 yrs. 2) dont know 3) b Thank you sir 🙏🙏
3. Only statement 2 is correct. 1st statement is instantly eliminated as current age of X is 42 and 8 years ago it would've been 42-8 = 34 which is not a multiple of 5. Hence, the age of Y would be in decimals which is not the case.
20:04 ans 23 22:49 ans 37 hona chaahiye but option me 38 h 26:39 ans 2 only 32:52 doubt if sham is 70 and Ramesh is 20 at present So one condition as per question that 10 years ago sham is thrice of ramesh that is 60= 3×20 is satisfied But another condition after 10 years sham will be twice of ramesh that is 80 is not equal to 2×20 (i e. 40)

But another condition after 10 years sham will be twice of ramesh that is
80 is not equal to 2×20 (i e. 40)

Ans At 23 her father get married.
22:52 Practice Question(2019)
Answer option (B)1994 hint taking reference point Meera's age in 2010. We get Meenu age in 2010 being 16 years
1st practice question answer is B (23)
2x+x=42 => x=14
If X=42 then Y=14
8 years ago X=42-8=34 then Y=14-8=6
After 14 years X=42+14=58 then Y=14+14=28
So Answer follows option B
42+14 = 58 😲😲

Question mein likha hai ki last year Mr X ki age square thi
And next year cube ho jaegi
Toh
Chote digits ke square se compare kr lenge for example
Square
2 ka 4
3 ka 9
4 ka 16
5 ka 25
6 ka 36
Cube
2 ka 8
3 ka 27
4 ka 64
5 ka 125
6 ka 216
Toh acc to que
Last year he was square of a number and next year he will be cube of a number
And if u check clearly
It's possible only on 25 and 27
So at present he is 26
Ek saal pehle 5 ka square (25)
Ek saal baad 3 ka cube
(27)
And then question says how many more years he have to wait that his age become cube of another number again
Cube
6 ka 36
7 ka 49
8 ka 64
9 ka 81
10 ka 100
Then out of options u can reach to answer
That 64-26 equals to 38
So answer is 38 years
Hope aapko samjh aaya hoga
