Ram is 5years elder than Lakshman who is 4 years elder than Bharath. The sum of their ages is 61. Find the age of Lakshman.
Answers
Answer:
Step-by-step explanation:
Let the age of Bharath be x.
Age of Laxman = x + 4
Age of Ram= x + 4 + 5
Equation :
(x) + (x + 4) +( x + 4 + 5) = 61
3x + 13 = 61
3x = 61 - 13 ( by transposition)
3x = 48
x = 48/3 ( by transpostion)
x = 16
Age of Bharat = x = 16
Age of Laxman = x + 4 = 16 + 4 = 20.
Answer: 20 years old
Step-by-step explanation:
If you use algebraic solution,
Lakshman will be N, Ram will be N+5 and Bharath will be N-4. The equation will be 3N+1=61. It will be 3N from lakshman(N), Ram N+5) and Bharath(N-4) so in total, there are three N.+1 was from subtracting 4 from 5 to simplify. =61 was from the statement THE SUM OF THEIR AGES IS 61. If you transpose +1 to =61, the equation will become 3N=61-1, the rule was if you going to transpose terms, their signs will change, from negative to positive and positive to negative. Now, the equation will become, 3N=60. To cancel out the 3 in 3N, divide both 3N and 60, so the answer will become N=20.
