The correct answer with a full explanation. Practice this interactively instead →
S जवळ काही रंगीबेरंगी शिंपले आहेत. यातील एक तृतीयांश शिवाय 14 जादा शिंपले तिने P ला दिले. P ने यातील एक तृतीयांश शिवाय 11 जादा शिंपले Q ला दिले. Q ने यातील एक तृतीयांश शिवाय एक जादा शिंपला तिच्या R या मित्राला दिला. जर R ला Q कडून 14 शिंपले मिळाले तर S कडे मुळात असलेल्या शिंपल्यांची संख्या निवडा. S is having some colourful sea shells. She gave one third of these shells and 14 more besides to P. P gave one third of these shells and 11 more besides to Q. Q gave one third of these shells and one more besides to her friend R. If R got 14 shells from Q then select the number of shells S originally has.
Working backwards from R: R got 14 shells. Q gave 1/3 + 1, so before Q, the number was (14 + 1) / (2/3) = 22. Similarly working backwards to P and S yields the original number of shells for S.
