Answer 1

38)

S = jumlah nilai

* S/28 = 76,5

S = 76,5 × 28

S = 2.142

* S/30 = 77,2

S = 77,2 × 30

S = 2.316

nilai intan+bintang

= 2.316 - 2.142

= 174

nilai intan 4 lebihnya dari nilai bintang

174-4 = 170

170:2 = 85

nilai bintang = 85

nilai Intan = 89

39)

nilai wati = 2/3 (nilai rahma)

nilai wati = 2/3 (96)

nilai wati = 64

nilai rini = 3/4 (nilai wati)

nilai rini = 3/4 (64)

nilai rini = 48

selisih nilai rini dan wati

= 64 - 48

= 16

A. 16
