The ages of rahul and haroon are in the ratio 7: 5.four years later the sum of their ages will be 56 years. find their present ages.

Rahul is 28, and Haroon is 20. 56-8=48,

4 is the right answer

Step-by-step explanation:

let the present age be 5x and 7x

after four years rahuls age = 5x + 4

                          haroons age =7x +4

                                                =5x + 4 + 7x + 4

                                                 =56

                                                 =12x +8 =56

                                                 =12x =48

                                                   x = 4

-4

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
