Question

The sum of two popitive numbers is 1840 18 40 % of the first number is equal to 75 % of the second number , what is the larger number among the two​

Answer 1

Answer:

let no.s be x and y

then x+y=1840

40%x=75%y

.4x=.75y

x=1.875y

put in eq 1

1.875y+y=1840

2.875y=1840

y=640

x+640=1840

x=1200

Answer 2

Answer:

1st number is greater than 2nd number

Step-by-step explanation:

1st number is greater than 2nd second number

Since 40 % of 1st = 75% of 2nd number .

Let me find two unknown number

Let X and Y be two +ve numbers

Given that ;

X + Y = 1840……………eqn-1

40%of X = 75% of Y

0.4X = 0.75Y

X = 0.75Y÷0.4

X = 1.875 Y …………………eqn-2

Sub eqn-2 in eqn-1

1.875Y + Y = 1840

2.875Y = 1840

Y = 1840/2.875

Y = 640

When Y = 640

X = 1.875 × 640

X = 1200

Check

X + Y = 1840

1200+640 = 1840

Hence 1st number is greater than 2nd number.
