Answer 4

A vendor who is an ex-mathematician has a number of apples and when he arranges them in rows of 3 he is left with one more, when he arranges them in rows of 5 again he is left with 1 more, Same happens with when he tries to arrange them in rows of 7 and 9 that is 1 apple is left extra.

But when he arranges them in a row of 11 he is left with none. Can u tell me

how many apples were there?

Ans. question says no. of apples when arrange in rows of 3,5,7,9 should leave only 1 apple & when in rows of 11 should leave nothing or

number of apples is exactly divided by 11 & (no.-1) is divided by

3,5,7,9

let the no. is X

then X-1 is l.c.m of 3,5,7,9 = 315

now let's check ,(315 + 1)/11 = 28.72 (not exactly divisible)

(315*2 + 1)/11 = 57.36 (not exactly divisible)

(315*3 + 1)/11 = 86 exact..

"the answer is 946."

9 : 28 : : 126 : _________

options are :

146

217

271

297

Ans (1) 9:28:126:?

9=((2^3)+1)

28=((3^3)+1)

and

126=((5^3)+1)

and

((6^3)+1)=217

therefore the answer is 217.

is it correct.

Ans (2) most important two quantities (9/28) & (126/?) have been

equated with each other i.e. ( :: is = )

now question becomes (9/28)=(126/?)

just cross multiply [ ? = (28*126)/9 ]

therefore the answer is "392"
