Question

A dietician, during her experiment, mixes two sample to make a third substitute. She mixes 40% of sample A and 70% of sample B. Initially, she has 60 gms of A and 110 gms of B, calculate the weight of the substitute C.

• A. $24$
• B. $77$
• C. $101$
• D. $170$

Answer 1

The correct option is C $101$

A dietician during her experiment

She mixed $40\%$ of sample $A$ in $60$ gm in sample $C$ $=$ $\frac{40}{100}\times 60=24$ gram

And she mixed $70\%$ of sample $A$ in $110$ gm in sample $C=$ $\frac{70}{100}\times 110=77$ grams

Then weight of substitute sample $C=24+77=101$ gms
