15. Divide 25 into two parts such that 7 times the first part added to 5 times the second part makes
139.
Divide 180 into two parts such that the first part is 12 less than twire the second part,​

Answer 1

Answer:

14. Let the sum of 1st consecutive odd no. be x

then 2nd consecutive odd no. = x+1

& 3rd consecutive odd no. = x+2

according to your question,

x + x + 1 + x + 2 = 75

or, 3x + 3 = 75

or, 3x = 75 - 3

or, 3x = 72

or, x = 72/3

x = 24

Hence the 1st consecutive odd no. =x = 24.

2nd consecutive odd no.= x+1=24+1

= 25.

& 3rd consecutive odd no.=x+2=24+2

= 26.
