Step-by-step explanation:
(a) Radhika got = x
She got three times and four more than pratim
= 3x + 22/30 + 4
(b) Radhika get = 3x + 22/30 + 4 = 0
= 3x + 142/30 = 0
= 3x = 30/142
=. × = 30/142 ÷ 3
=. x = 30/142 × 1/3
=. x = 10/142
=. x =. 5/71
(c) Archak got = y
Total marks = 30
= 1/3 times of 30
{algebraic expression} :- y = 1/3 of 30
y = 1/3 ×30
y = 10
Hence the answer is done.
