Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Mrs. Wong sold 200 cakes altogether.

More Explanation :

Ratio is a relationship of two quantities, usually expressed as quotient of one divided by the other.

The ratio is usually expressed as a fraction.

To be known :

Shop A, Shop B, and Shop C

Shop A bought 20% of the cakes

Shop B bought 4 times as many cakes as Shop C

Shop B bought 88 more cakes than Shop A

To be asked :

Total cakes sold altogether = . . . . ?

To be answered :

Shop A = 20%

So that Shop B + Shop C = 60%

Shop B = 88 + Shop A

Shop B = 4 times Shop C, so that B = 4C

A = 20%

B + C = 80%

4C + C = 80%

5C = 80%

C = \tt \dfrac {80}{5}

C = 16%

B = 4 times C

B = 4 × 16%

B = 64%

B = 88 + A

64% \tt x = 88 + 20% \tt x

88 = 64% \tt x - 20% \tt x

88 = 44% \tt x

x = \tt \dfrac {88 \times 100}{44}

x = 200

Conclusion :

Mrs. Wong sold 200 cakes altogether.
