Text Solution

Verified by Experts

The correct Answer is:
C

माना कि प्रारंभ में कुल 100 आदमी उद्यान में आते थे।
`therefore` कुल राजस्व = `100 xx 0.25 = Rs. 25`
मूल्य कम करने के पश्चात टिकट का मूल्य = 0.20
कुल राजस्व = `(25 xx 128)/(100) = Rs. 32`
`therefore ` आगंतुकों की संख्या =`(32 xx 100)/(20) = 160`
`therefore ` आगंतुकों की संख्या में
% वृद्धि = `(160-100)/(100) xx 100= 60%`
Note-Que में टिकट की बिक्री की जगह राजस्व में वृद्धि होगा।
