Katse e ja disose tsa borobongwe mo metsotsong e le 30. Ntswa e kgona go ja disose tse di kana mo palong ya 2/3 ya nako e e jewang ke katse. Bala palogare ya nako e di e tsayang go ja disose. 

The restaurant has 170 normal chairs and 23 chairs for babies. If 20 of the normal chairs and 13 of the baby chairs were sent to the carpenter for repair, how many chairs does the restaurant have left?
Fa katse e tsaya metsotso e le 30 go ja disose, ntswa yone e tsaya 2/3*30 = <<30*2/3=20>>20 metsotso.
Palogare ya nako e katse le ntswa di e tsayang go ja disose ke 20+30 = <<20+30=50>>50 metsotso.
Palogare ya nako mo metsotsong e di e tsayang go ja disose ke 50/2 = <<50/2=25>>25 metsotso.
#### 25

Before sending the chairs and baby chairs to the carpenter the restaurant had 170 + 23 = <<170+23=193>>193 chairs.
They sent 20 + 13 = <<20+13=33>>33 chairs to the carpenter.
Now, they have 193 - 33 = <<193-33=160>>160 chairs left.
