Answer 1

A N S W E R :

• Akshita used 27/56 part of the money in buying the car.

Given :

• Akshita invested

• 3/8 in share market

• 1/7 in real estate

• Remaining in buying a car

To find :

• Part of money she used in buying a car ?

Solution :

• Let be fixed amount be " x "

According to the question,

• Investment of share market = 3/8 of x

• Investment of real estate = 1/7 of x

Now,

• Part of money used in buying the car

=> Fixed amount - (Investment in share market + Investment of 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

Hence,

• Akshita used 27/56 part of the money in buying the car.
