is it B for the 56

rishavraj (rishavraj):

@mathmath333 ???

OpenStudy (mathmath333):

yes i want help for 57

rishavraj (rishavraj):

okkkk lets try tht :P

OpenStudy (anonymous):

Well if you know Zaheer is 10. Then you can know Yog is 11. You also will know 2*10 = Wahida = 20 And Elle = 3 * 11 = 33 So, A works out.

OpenStudy (anonymous):

But, B makes it more certain. since

rishavraj (rishavraj):

@Zelda its noth mentiond the Yogesh is 1 year older than zaheer

OpenStudy (anonymous):

@rishavraj Getting to that. So if you know they're same number of years. Then Say Yog = 10 years older than zaheer, since 20 - 10 =10. So Elle = 3*20 = 60

OpenStudy (anonymous):

So if you know both A and B for #57, it's enough to estimate it.

rishavraj (rishavraj):

@mathmath333 makes sense

OpenStudy (mathmath333):

i yam still reading

rishavraj (rishavraj):

lol ok....take ur time :P

OpenStudy (mathmath333):

why she took yogi=10 yrs

rishavraj (rishavraj):

see if we consider option A and B then Zaheer's age = 10 and Wahida's would be 20....and according to option B both Wahida and Yogesh are older than Zaheer by the same number of years.....so even Yogesh age would be 20 ....

OpenStudy (mathmath333):

ok i get that now thnlks

rishavraj (rishavraj):
