3% of 33 + 4% of 44 = x% of y
which is the correct set of x and y respectively

OPtion

1) 5,56
2) 6,66
3) 4,54
4) 55,5
6) 2,34
7) 2,22
8) 7,76
9) 66,6
10) 5,50

Solution

3% of 33 = 3*33/100
4% of 44 = 4*44/100
3% of 33 + 4% of 44 = 11/100(3^2+4^2) = 11/100*5^5

25*11/100 = 55*5/100

So possible sets for x,y are
(25,11) (11,25) (5,55) (55,5) (1,275)(275,1)

correct option is 55,5

Correct Option: 4 Best Solution (26)

(33*3/100)+(44*4/100)=y*x/100,
==>(99/100) + (176/100)=xy/100,
==>275=xy ==> xy=55*5,
Therefore, 55,5 is the correct set of x and y respectively.

3*33+4*44=275 we can ignore 100 because it is common term for both sides.So we have to find x and y which makes 275 and the answer is 5 and 55

Solving the left hand side equation:-
3% of 33 + 4% of 44
(3/100)*33+(4/100)*44
((3/100)*3*11)+((4/100)*4*11)
taking common from both the expressions
(11/100)((3*3)+(4*4))
(11/100)25
(11/100)(5*5)
multiplying one 5 with (11/100)
(55/100)*5
Anything divided by 100 represents percentage so, the above equation represts
55%of5

Alternatively, we can calculate the value of the left hand side expression and calculate the value in the options.:-)

K.Sathyavathi   14 years AGO

(3/100)*33+(4/100)*44=11/4
from option if we substitute value for x and y we get 11/4 for 55,5.

Raushan Kumar   14 years AGO

given:3% of 33 + 4% of 44 =((3/100)*33)+((4/100)*44)=99/100+176/100=275/100=(55*5)/100=(55/100)*5=55% of 5

so, answer: 3% of 33 + 4% of 44 = x% of y
= 55% of 5
so, x=55 y=5
