Let the number be x.
Then,x- 35= (80/100)x
x-(4/5)x = 35 ⇒ x/5 = 35 ⇒ x = 175
Now, 4/5 of x = 4/5 × 175 = 140
Then,x- 35= (80/100)x
x-(4/5)x = 35 ⇒ x/5 = 35 ⇒ x = 175
Now, 4/5 of x = 4/5 × 175 = 140
CTET Maths MCQ - Algebra
Let the number be 100.
After increasing by 10%, the number
= 110% of 100 = 110 .
After decreasing by 10%, the number
= 90 % of 110 = 99 .
Decrement in number = 100 -99 = 1 .
Percentage decrease = (Decrease in number / Original number ) x 100%
= (1/100) x 100% = 1%
CP = 75000 Rs.
Loss percentage = 15% .
SP = (100 -15)% of 75000 .
= 85/100 x 75000 = 63750 Rs
