KnowledgeBoat · Accepted Answer

(i) a, b, c, d are in proportion Hence, a = bk, c = dk. Since, L.H.S. = R.H.S. Hence proved. (ii) a, b, c, d are in proportion Hence, a = bk, c = dk. Putting value of a = bk, Putting value of c = dk, Since, L.H.S. = R.H.S. Hence proved. (iii) a, b, c, d are in proportion Hence, a = bk, c = dk. Since, L.H.S. = R.H.S. Hence proved. (iv) a, b, c, d are in proportion Hence, a = bk, c = dk. Since, L.H.S. = R.H.S. Hence proved. (v) a, b, c, d are in proportion Hence, a = bk, c = dk. Since, L.H.S. = R.H.S. Hence proved. (vi) a, b, c, d are in proportion Hence, a = bk, c = dk. Since, L.H.S. = R.H.S. Hence proved. (vii) a, b, c, d are in proportion Hence, a = bk, c = dk. Since, L.H.S. = R.H.S. Hence proved. (viii) a, b, c, d are in proportion Hence, a = bk, c = dk. Since, L.H.S. = R.H.S. Hence proved.
