akshita invested 3/8 of a fixed amount in share market, 1/7 in real estate and remaining in buying a car. what part of money did she use in buying a car? please answer by taking x not 1
Answers
Let the fixed amount be "x"
According to the question,
Investment in share market= 3/8 of x
Investment in real estate= 1/7 of x
Now,
Part of money used in buying the car
= Fixed amount - (investment in share market + investment in real estate)
= x - (3/8 of x + 1/7 of x)
= x - (3x/8 + x/7)
= x - [(3x × 7) + (x × 8) / 56] {LCM of 8 and 7 is 56}
= x - (21x + 8x / 56)
= x - (29x/56) = x/1 - 29x/56
= (x × 56) - 29x / 56 {LCM of 1 and 56 is 56}
= 56x - 29x / 56 = 27x/56
= 27/56 of x
= 27/56 part of the fixed amount
Therefore, Akshita used 27/56 part of the money in buying the car.
Let fixed be x .
3/8 of x = in share market = 3x/8
1/7 of x = in real estate = x/7
remaining = x - x/7 - 3x/8
=> (56x-8x-21x)/56
=> (56-29)x/56
=> 27/56
part of money used = 27/56. Ans.
