Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
In a fruit salad, there are raspberries, green grapes, and red grapes. There are seven more than 3 times the number of red grapes as green grapes. There are 5 less raspberries than green grapes. If there are 102 pieces of fruit in the salad, how many red grapes are in the salad?

### Response:
 องุ่นเขียว = G
องุ่นแดง = 3G + 7
ลูกเสือราสเบอร์รี่ = G - 5
G + 3G + 7 + G - 5 = 102
5G + 2 = 102
5G = 100
G = <<20=20>>20
มีองุ่นเขียว 20 ลูก
มีองุ่นแดง 3 * 20 + 7 = <<3*20+7=67>>67 ลูก
