Q5Written answer
Sangeeta went to the market with her grandpa.
She looked at the prices and said to her grandpa —
(a) Ghee is Rs 102 rupees costlier than biscuits.
(b) Price of oil and ghee altogether is more than Rs 200.
(c) Price of ghee and 10 kg rice is less than Rs 300.
(d) Oil costs Rs 40 more than a pack of biscuits.
Is Sangeeta right?
Can you find this without using paper and pencil?
Show solutionHide solution
Worked solution
(a) Cost of Ghee = Rs 127
Cost of Biscuits= Rs 25
Amount by which Ghee is costlier than biscuit = 127 – 25 = 102
Thus, Sangeeta is correct.
(b) Price of Ghee = Rs 127
Price of Oil = Rs 70
- 127 + 70 = Rs 197
So, Sangeeta is wrong in saying that the price of ghee and oil altogether is more than 200.
(c) Price of Ghee = Rs 127
Price of 10 kg Rice = Rs 150
The sum is Rs 277, which is less than 300.
Hence, Sangeeta is correct.
(d) Cost of biscuits= Rs 25
Cost of Oil = 70
No, the difference between the prices is Rs 45.
So, Sangeeta is incorrect.
Yes, we can do the calculations without using paper and pencil.
