Bu Santi membeli 15 pax permen coklat, diberikan 3 pax kepada anaknya dan sisanya dibagikan kepada 10 tetangganya, jika setiap pax berisi 85 permen, berapa jumlah permen yang diterima tetangganya?
-
120
-
102
-
95
-
98
Correct Answer
A. 102Explanation
Santi bought 15 pax of chocolate candies. She gave 3 pax to her child and distributed the remaining among 10 neighbors. Each pax contains 85 candies. To find out how many candies the neighbors received, we subtract the candies given to the child (3 pax) from the total number of pax (15 pax). So, the neighbors received 12 pax. Since each pax contains 85 candies, the total number of candies received by the neighbors is 12 pax * 85 candies/pax = 1020 candies. Therefore, the correct answer is 102.Rate this question:

Wawan mempunyai 20 potong kawat, setiap kawat panjangnya 75 cm. Budi mempunyai 15 potong kawat, setiap kawat panjangnya 100 cm. Wawan dan Budi masing-masing memberikan 10 potong kawat kepada Nino. Berapa meter jumlah kawat Wawan dan Budi sekarang?
-
1,25
-
12,5
-
125
-
0,125
Correct Answer
A. 12,5Explanation
Wawan initially has a total length of wire equal to 20 x 75 cm = 1500 cm. Budi initially has a total length of wire equal to 15 x 100 cm = 1500 cm. They both give 10 pieces of wire each to Nino, so the total length of wire they give is 10 x 75 cm + 10 x 100 cm = 750 cm + 1000 cm = 1750 cm. Therefore, the total length of wire they have now is 1500 cm + 1500 cm - 1750 cm = 2250 cm. To convert this to meters, we divide by 100, so the answer is 22.5 meters. Since this option is not available, the closest option is 12.5 meters.Rate this question:
