Answer:
✬ Length = 173 cm ✬
Given:
Total pieces of ribbon is 19.
7 pieces are of 11 cm.
Rest (12) pieces are of 8 cm.
To Find:
What was original the length of ribbon ?
Solution: Let original length of ribbon was x cm. Therefore,
Length of ribbons of 11 cm = No. of pieces(11)
Total length = 7(11)
77 cm....(1)
Length of ribbons of 8 cm = No. of pieces(8)
Total length = 12(8)
96 cm...(2)
A/q
Original ribbon = Equation 1 + Equation 2
x = Sum of length of ribbons (11 cm and 8 cm)
x = 77 + 96
x = 173 cm
Hence, original length of ribbon at first was 173 cm. (Option a is correct)
