Question

. The reciprocal of the additive inverse of -1/3
is added to the multiplicative inverse of 15/7 to get 1/90 of the income of Mr. X. If he spends 3/4 of his income, what is the reciprocal of 1/10 of his savings.​

Answer 1

Answer:

1/702

Step-by-step explanation:

additive inverse of -1/3=1/3

reciprocal of 1/3=3

multiplicative inverse of 15/7=7/15

Let the income of Mr.X be y,

3+7/15=y/90

LCM=15

45/15+7/15=y/90

52/15=y/90

52/15×90=y

52×6=y

312=y

income of Mr.X=312×90=28080

spendings of Mr.X=3/4×28080

=3×7020

=21060

savings=28080-21060=7020

1/10 of savings=1/10×7020

=702

reciprocal=1/702
