age was four times of Shyam. The
difference between their ages is​

Answer 1

Answer:

Step-by-step explanation:

Ram = R is 4/3 = 1,33 times older than Shyam (S)

therefore S = 1/1,33R = 0,75R

so

R + 30 = S + 30 + 10

R - S = 10 but S = 0,75R

R - 0,75R = 10

R (1 - 0,75) = 10

R = 40 Ram is 40 years old

S = 40/1,33 = 30 Shyam is 30 years old

Answer 2

Answer:

LET RAMS AGE BE X

SHYAM'S AGE=Y

ATQ

X+Y=75 (1)

10 YEARS AGO

X-10= 4(Y-10)

X-10=4Y-40

30= 4Y-X

30 = 4Y-(75-Y)   (USING 1)

30= 4Y-75+Y

105= 5Y

Y= 21

IN EQ 1

X= 75-21= 54

DIFF BTWN THEIR AGES= 54-21= 33
