Download Solution PDFदिलेले आहे:
19, 57, 81 आणि y हे समानुपाती आहेत.
वापरलेले सूत्र:
जर चार संख्या a, b, c आणि d समानुपाती असतील, तर a/b = c/d.
गणना:
येथे, a = 19, b = 57, c = 81 आणि d = y.
सूत्रानुसार:
⇒ 19 / 57 = 81 / y
तिरकस गुणाकार करून:
⇒ 19y = 57 × 81
⇒ 19y = 4617
दोन्ही बाजूंना 19 ने भागून:
⇒ y = 4617 / 19
⇒ y = 243
पर्याय 4 योग्य आहे.
