No of apples plucked on Day 1 (1+2+3) + (4+5+6) – (2+3+4+5+6)= 130+145-225 = 50 Day 2 (2+3+4)+ (5+6+7)- (3+4+5+6+7) = 150 + 140 -265 = 25 Day 3 (1+2+3) + (3+4+5) – (1+2+3+4+5+6) = 130+ 165 -240 = 55 Day 4 (2+3+4) + (4+5+6) – (2+3+4+5+6) = 150+ 145 -225 =70 Day 5 (3+4+5) + (5+6+7) – (3+4+5+6+7) = 165 + 140 -265 = 40 Day 6 (4+5+6) + (6+7+8) – (4+5+6+7+8) = 145-160-270 =35 Day 7 (5+6+7) + (7+8+9) – (5+6+7+8+9) = 140+175-250=65 Day 8 (6+7+8) +(8+9+10) – (6+7+8+9+10) = 160+155-255=60 Day 9 (4+5+6) + (7+8+9) – (4+5+6+7+8) = 145 + 175 -270 = 50 Day 10 (5+6+7) + (8+9+10) – (5+6+7+8+9) = 140 + 155 – 250 = 45 No of apples plucked on day 6 is 35.
